[git] Review all functions but ones using `git fsck` 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`. 2018-01-10 10:25:25 -05:00			`# vim:et sts=2 sw=2 ft=zsh`
