Add home directory expansion for SSH key filepaths. This allows the
`signing.key` configuration value to work more universally across both
Linux and macOS without requiring an absolute path.
This moved and renamed the previous `expand_git_path` function to a more
generic location, and the prior use was updated accordingly.
When the caller needs a formatter, it's because they're doing
something non-trivial. When the user passed `--quiet` (see upcoming
patch), we should ideally skip doing related work for print the
formatting output. It helps if the `Ui` object doesn't even return a
`Formatter` then, so the caller is forced to handle the quiet case
differently.
Thanks to Yuya for the suggestion.
It's inconsistent that some warnings have headings and some don't, and it seems
the choice is arbitrary. Let's unify the style. There are two exceptions:
1. continued line following labeled message,
2. "unrecognized response" followed by prompt.
The lowercase "warning: " is unified to "Warning: " as it is the jj's
convention afaik.
The _default() suffix could be dropped from these methods, but it's probably
better to break the existing codebase for the moment. Otherwise, the caller
might do writeln!(ui.warning(), "Warning: ..").
The existing .hint() method is renamed to .hint_no_heading() to clarify that
it's not the default choice to print a hint. I'll add .hint_default() later,
which will be the shorthand for .hint_with_heading("Hint: ").
The error output gets more verbose because all gix error sources are printed.
Maybe we'll need a better formatting, but changing to multi-line output doesn't
look nice either.
Gerrit also needs to be able to push low-level refs into upstream remotes, just
like `jj git push` does. Doing so requires providing callbacks e.g. for various
password entry mechanisms, which was private to the `git` command module.
Pull these out to a new module `git_utils` so we can reuse it across the two
call sites.
This also moves a few other strictly Git-related functions into `git_utils`
as well, just for the sake of consistency.
