This complements the changes done in the last commit, and also fixes the
`glg` output, and removes the now unnecessary `--date=relative`
parameter from `glG`.
Although I insisted on the `--long-option` format on 8669a4f, I think
`rm -rf` is pretty common and recognizable, so revert to that.
Add missing aliases to README.md, and improve description of existing
ones. The main improvement is trying to be more concise, so instead of
repeating "records changes to the repository" multiple times, simply say
"commits", for example. Also try to use words that match the alias
letters, so for "gcs" say "shows" instead of "displays", for example.
as there are multiple solutions to list the lost commits and stashes,
but I could not find reliable ones. See
https://stackoverflow.com/q/89332/2654518.
Well, the current `git-commit-lost` and `git-stash-dropped`
implementations don't accurately work at least on the repositories I'm
working with.
The `git-hub` functions where removed at dcc3265, but aliases and docs
remained. Remove these.
Remove line break from `_git_log_oneline_format`, so it really occupies
one line. And change date format in `glG` output from committer date
(`%cd`) to relative author date (`%ar`) to conform with other formats.
Refactor remaining functions. Most of the changes refer to using the
already existing git error messages and return codes, instead of having
code that creates that. (Error messages for 'not in a git repository'
where not even consistent among functions, and there's were I started
this...)
The most drastic changes can be seen in `git-root`, then in `git-dir`
and `git-stash-clear-interactive`.
as they were only being used by gitster prompt theme and kept for
Oh-My-Zsh compatibility. The newly introduced git-info module (inspired
by the git-info Prezto function) provides a more powerful
implementation than the Oh-My-Zsh inspired git_prompt_info.
Updated gitster to use the git-info module.
Closes#124
