As suggested by @crackcomm on discord, use eprintln!() to print warnings
to avoid messing up template output, e.g.:
jj --no-pager --ignore-working-copy show --tool true -T change_id -r rv...
rv...ignoring git submodule at "some/submodule"

The return type T doesn't have to be a literal, and I'm going to use this
function to reparse fileset expression. We might also want to add another
expect_literal_with() helper that parses enum-like string value.
This not only makes the output easier to read, but also protects against
implementation detail changes in `write!` when used with a format
string (especially, how many times and with what strings it calls the
underlying writer).
Maybe it'll also be good to keep RevsetExpression::Union(_) flattened, but
that's not needed to get around stack overflow. The constructed expression
tree is balanced.
test_expand_symbol_alias() is slightly adjusted since there are more than
one representation for "a|b|c" now.
Fixes#4031
Partially resolve a 1.5‐year‐old TODO comment.
Add opt‐in syntax for case‐insensitive matching, suffixing the
pattern kind with `-i`. Not every context supports case‐insensitive
patterns (e.g. Git branch fetch settings). It may make sense to make
this the default in at least some contexts (e.g. the commit signature
and description revsets), but it would require some thought to avoid
more confusing context‐sensitivity.
Make `mine()` match case‐insensitively unconditionally, since email
addresses are conventionally case‐insensitive and it doesn’t take
a pattern anyway.
This currently only handles ASCII case folding, due to the complexities
of case‐insensitive Unicode comparison and the `glob` crate’s lack
of support for it. This is unlikely to matter for email addresses,
which very rarely contain non‐ASCII characters, but is unfortunate
for names and descriptions. However, the current matching behaviour is
already seriously deficient for non‐ASCII text due to the lack of any
normalization, so this hopefully shouldn’t be a blocker to adding the
interface. An expository comment has been left in the code for anyone
who wants to try and address this (perhaps a future version of myself).
`tx.format_commit_summary()` can be expensive because it needs to build
an IdPrefixContext now, so it's best to avoid formatting instruction
messages unless they are actually required.
I don't think there's a possibility that uncommon_shared_words can become
non-empty by trimming the same amount of lines from both sides. Well, there's
an edge case regarding max_occurrences, but that shouldn't matter in practice.
Patience diff starts by lining up unique elements (e.g. lines) to find
matching segments of the inputs. After that, it refines the
non-matching segments by repeating the process. Histogram expands on
that by not just considering unique elements but by continuing with
elements of count 2, then 3, etc.
Before this commit, when diffing "a b a b b" against "a b a b a b", we
would match the two "a"s in the first input against the first two "a"s
in the second input. After this patch, we ignore the "a"s because
their counts differ, so we try to align the "b"s instead.
I have had this commit lying around since I wrote the histogram diff
implementation in 1e657c5331. I vaguely remember thinking that the
way I had implemented it (without this commit) was a bit weird, but I
wasn't sure if this commit would be an improvement or not. The bug
report from @chooglen today of a case where we behave differently from
Git is enough to make me think that we make this change after all.
#761
This is adapted from Breezy/Python patiencediff. AFAICT, Git implementation is
slightly different (and maybe more efficient?), but it's not super easy to
integrate with our diff logic. I'm not sure which one is better overall, but I
think the result is good so long as "uncommon LCS" matching is attempted first.

This patch prevents some weird test changes that would otherwise be introduced
by the next patch.
I've run into change ID prefixes being 4-5 characters instead of the
usual 1-2 characters in commands like `jj duplicate` and `jj split`
fairly often, and it seems like this should resolve that.
For the same reason as the previous commit.
Created and moved stats are printed separately because it's unusual to do both
within one "branch set" invocation.
For the same reason as cdc0cc3601. This will help notice problems like wrong
target revision.
The warning for multiple branches is reorganized as a hint for "-r" option,
which I think is the main purpose of this warning. Unlike "squash", we don't
check if an argument can be parsed as a revset because branch name is usually
a valid symbol expression.
The output looks somewhat similar to color-words diffs. Unified diffs are
verbose, but are easier to follow if adjacent lines are added/removed + modified
for example.
Word-level diffing is forcibly enabled. We can also add a config knob (or
!color condition) to turn it off to save CPU time.
I originally considered disabling highlights in block insertion/deletion, but
that wasn't always great. This can be addressed separately as it also applies
to color-words diffs. #3958
Forgetting a workspace removes its working-copy commit, so it makes
sense for it to be abandoned if it is discardable just like editing a
new commit will cause the old commit to be abandoned if it is
discardable.
Currently, if two workspaces are editing the same discardable commit and
one of them switches to editing a different commit, it is abandoned even
though the other workspace is still editing it. This commit treats
workspaces as referencing their working-copy commits so that they won't
be abandoned.
