This doesn't change the way @git branches are stored in `git_refs` as opposed
to inside `BranchTarget` like normal remote-tracking branches. There are
subtle differences in behavior with e.g. `jj branch forget` and I'm not sure
how easy it is to rewrite `jj git import/export` to support a different
way of storage.
I've decided to call these "local-git tracking branches" since they track
branches in the local git repository. "local git-tracking" branches sounds a
bit more natural, but these could be confused with there are no remote
git-tracking branches. If one had the idea these might exist, they would be
confused with remote-tracking branches in the local git repo.
This addresses a portion of #1666
This follows up on 5c703aeb0397b560a383bdd57a87235834074b64.
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.
Compare after:
and before:
@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 ◎-`.
This eliminates ambiguous parsing between "func()" and "expr ()".
I chose "++" as template concatenation operator in case we want to add
bit-wise negate operator. It's also easier to find/replace than "~".
