I considered adding RefTarget template type, but some of the methods naturally
fit to RefName. For example, a conflicted branch name is decorated as "??", so
it makes sense to add branch.conflict() instead of branch.target().conflict().
I'm not pretty sure how many RefName methods we'll need to add to port the
current branch listing, but there will be .tracked(), .tracking_local_present(),
.ahead_by(), and .behind_by().
I'm going to add more detailed output there. This is a step towards "branch
list" template. "tag list -T" wouldn't be that useful, but it shares primitives
with "branch list -T".
I'm going to add ref_name.target*() template methods so the commit templater
can be reused for branches/tags templates. RefTarget could be looked up by
(name, kind) pair, but it's simpler to store it in RefName.
Before this patch, we would abandon the source commit if it became
empty after applying the reverse diff. This changes that condition to
the equivalent condition of the selected tree being the source
commit's original tree. This will help us rewrite the code to use
`transform_descendants()`.
The `move_commits` function accepts a set of target commits to shift to
a new location given by `new_parents` and `new_children`. The roots of
the target set will be reparented onto `new_parents`. `new_children`
will then be reparented onto the heads of the target set.
The commits will be rebased in reverse topological order based on the
new set of parents of each commit, which avoids the need for multiple
sets of rebase operations.
Spotted while experimenting with "jj tag list -T". The description_placeholder
alias could be changed to function taking a Commit object, but I feel it's odd.
Conceptually, the placeholder could also be used in "op log" templates.
Since fileset/revset/template expressions are specified as command-line
arguments, it's sometimes convenient to use single quotes instead of double
quotes. Various scripting languages parse single-quoted strings in various ways,
but I choose the TOML rule because it's simple and practically useful. TOML is
our config language, so copying the TOML syntax would be less surprising than
borrowing it from another language.

While I like strict parsing, it's not uncommon that we have to deal with file
names containing spaces, and doubly-quoted strings such as '"Foo Bar"' look
ugly. So, this patch adds an exception that accepts top-level bare strings.
This parsing rule is specific to command arguments, and won't be enabled when
loading fileset aliases.
When you use e.g. `git switch` to check out a conflicted commit,
you're going to end up with the `.jjconflicts-*` directories in your
working copy. It's probably not obvious what those mean. This patch
adds a README file to the root tree to try to explain to users what's
going on and how to recover.
The authoritative information about conflicts is stored in the
`jj:trees` commit header. The contents of conflicted commits is only
used for preventing GC. We can therefore add contents to the tree
without much consequence.
I will be updating `rebase -r` to avoid simplifying ancestor merges in a
subsequent commit, which will cause existing tests to fail for the Git
backend due to ancestor merges with the root commit.
I'm not sure if this was an intentional omission, but I think it would be
useful to have `-e` as a short flag for `--edit`. I don't usually edit commits,
but I do use `prev` and `next` with edit to navigate to a commit that I want to
squash. Often this is easier than typing `--from` and `--into` plus the change
IDs.
If people want to edit commits we shouldn't stand in their way.
This is following on the rewrite for `parallelize`.

Since rebase_descendants from rebase.rs is no longer used outside of that file,
it can be made private again.
In a future commit these tests will run with both `jj commit` and `jj new` since
both will have the same semantics for advancing the branch pointer.
Parameterizing the tests allows us to run both variants without duplicating the
test bodies. Since the commit IDs are different when `jj describe` + `jj new`
is used instead of `jj commit`, this commit also drops the commit IDs from the
test snapshots. This is fine because the commit IDs are not important for these
tests.
## Feature Description
If enabled in the user or repository settings, the local branches pointing to the
parents of the revision targeted by `jj commit` will be advanced to the newly
created commit. Support for `jj new` will be added in a future change.
This behavior can be enabled by default for all branches by setting
the following in the config.toml:
```
[experimental-advance-branches]
enabled-branches = ["glob:*"]
```
Specific branches can also be disabled:
```
[experimental-advance-branches]
enabled-branches = ["glob:*"]
disabled-branches = ["main"]
```
Branches that match a disabled pattern will not be advanced, even if they also
match an enabled pattern.
This implements feature request #2338.
Maybe it's personal preference, but the hash sign looks bigger compared to
the normal "o" nodes, and is slanted. This makes immutable commits stand out
too much. I think "+" is closer to the diamond character used in the unicode
template.
