32396: _git: fix __git_committish_range_{first,last} and __git_is_committish_range
- Ranges with 3 dots would always fail, because the non-greedy
expansion %..(.|)* in __git_committish_range_first would only
remove '..' and never three dots. 'a...b' would end up in 'a.'.
Use ${${1%..*}%.} instead.
- Use a similar approach for __git_committish_range_last.
- Wrap them in another expansion to replace empty results with 'HEAD'.
Git man-page states omitted range ending are being replaced with
HEAD. This rule has to be followed to make completions like
'git log foo.. -- <tab>' work properly.
- Add an additional check to make sure none of the extracted first/last
parts contain additional '..' in invalied ranges such as 'a..b..c'.
This gets rid of the 'TODO:' and ideally saves a few unneded
calls to git rev-parse.
