e1c57338a1 revset: split out no-args head() to visible_heads()
The `heads()` revset function with one argument is the counterpart to
`roots()`. Without arguments, it returns the visible heads in the
repo, i.e. `heads(all())`. The two use cases are quite different, and
I think it would be good to clarify that the no-arg form returns the
visible heads, so let's split that out to a new `visible_heads()`
function.

0e2579ee6a Switch graph node to use for commit instead of
This follows up on 5c703aeb03.

The only reason for this change is that, subjectively, the result looks better to me. I'm not sure why, but I couldn't get used to the old symbol in spite of its seeming reasonableness. It felt really bold and heavy.

If people agree, we can wait until we need to update the screenshots for some other reason before merging this. Sorry I didn't figure this out while the discussion about the referenced commit was going on.

I'm not 100% certain how many fonts support each symbol. Please try it out and let me know if it doesn't work for you.

0532301e03 revset: add latest(candidates, count) predicate
This serves the role of limit() in Mercurial. Since revsets in JJ is
(conceptually) an unordered set, a "limit" predicate should define its
ordering criteria. That's why the added predicate is named as "latest".

Closes #1110

ddeb645d7f cli: provide hint for typo of revset function name
This is similar to what Mercurial does. The similarity threshold is copied
from clap, but we might want to adjust it later.

5c703aeb03 cli: replace o as graph node by when using unicode graph
@joyously found `o` confusing because it's a valid change id prefix. I
don't have much preference, but `●` seems fine. The "ascii",
"ascii-large", and "legacy" graph styles still use "o".

I didn't change `@` since it seems useful to have that match the
symbol used on the CLI. I don't think we want to have users do
something like `jj co ◎-`.

038497638f revset: parse keyword arguments, accept remote_branches(remote=needle)
The syntax is identical to Mercurial's revset, which is derived from Python.

78227dc7bc revset: consolidate argument parsing functions
The added expect_arguments() is basically a copy from the template_parser.
I'll reimplement it to support keyword arguments, so I don't care much about
the current implementation.

I leave expect_no/one_argument() as wrappers because parsing 0/1 arguments
is pretty common.

Error messages are slightly changed. I personally prefer not to add extra
code for singular/plural handling, but if we do, I'll add 'if N == 1' case.

3ccdd1f98a tests: pass string instead of bytes to add_config()
I don't think need to write non-UTF8 bytes to our config files. If we
ever do (maybe to test that we give the user a reasonable error
message), we add a custom function for that.

a7541e1ba4 repo: add workaround for shortest prefix calculation of root ids
This is ugly, but we need a special case because root_change_id and
root_commit_id aren't equal but share the same prefix bytes. In practice,
no one would care for the shortest root id prefix, but we'll need to deal
with a similar problem when migrating prefix id resolution to repo layer.

7cd01b27a7 revset: parse hg-like '-'/'+' infix operators and show hint
Suggested by @arxanas.

Actually, it's easier to support these infix ops than erroring out, but I
don't want to make revset syntax more cryptic. "x- y" can't be handled by
this rule because "x-" is parsed as a parents expression.

48d10d648c revset: add unary negate (or set complement) operator '~y'
Because a unary negation node '~y' is more primitive than the corresponding
difference node 'x~y', '~y' is easier to deal with while rewriting the tree.
That's the main reason to add RevsetExpression::NotIn node.

As we have a NotIn node, it makes sense to add an operator for that. This
patch reuses '~' token, which I feel intuitive since the other set operators
looks like bitwise ops. Another option is '!'.

The unary '~' operator has the highest precedence among the set operators,
but they are lower than the ranges. This might be counter intuitive, but
useful because a prefix range ':x' can be negated without parens.

Maybe we can remove the redundant infix operator 'x ~ y', but it isn't
decided yet.

70292f79b7 revset: implement function alias expansion
Function parameters are processed as local symbols while substituting
alias expression. This isn't as efficient as Mercurial which caches
a tree of fully-expanded function template, but that wouldn't matter in
practice.

correctly, it won't have any legal effect, but maybe it still helps

8b00a64ab2 cli: load revset aliases from config file
Aliases are loaded at WorkspaceCommandHelper::new() as it's easier to warn
invalid declarations there. Not all commands use revsets, but many do, so
I think it's okay to always pay the loading cost. Parsing the declaration
part (i.e. a symbol) should be fast anyway.

The nested error message isn't super readable, but seems good enough.

Config syntax to bikeshed:
- naming: [revset-alias] vs [revset-aliases] ?
- function alias will need quotes: 'f(x)' = 'x'

ce3397c2cb revset: combine operator parsing steps
I'm thinking of adding alias expansion at this stage, and it would be a bit
tedious to pass around mutable context by function parameter. So let's reduce
the number of the intermediate functions.

This also produces a better error message.

1717690a64 revset: leverage SOI/EOI markers to detect incomplete parser input
The error message is still a bit cryptic, but I don't think it's worse than
the original "incomplete parse" error.
