completion: let 'for-each-ref' sort remote branches for 'checkout' DWIMery
When listing unique remote branches for 'git checkout's tracking
DWIMery, __git_refs() runs the classic '... |sort |uniq -u' pattern to
filter out duplicate remote branches.
Let 'git for-each-ref' do the sorting, sparing the overhead of
fork()+exec()ing 'sort' and a stage in the pipeline where potentially
relatively large amount of data can be passed between two subsequent
pipeline stages.
This speeds up refs completion for 'git checkout' a bit when a lot of
remote branches match the current word to be completed. Listing a
single local and 100k remote branches, all packed, best of five:
On Linux, before:
$ time __git_complete_refs --track
real 0m1.856s
user 0m1.816s
sys 0m0.060s
After:
real 0m1.550s
user 0m1.512s
sys 0m0.060s
On Windows, before:
real 0m3.128s
user 0m2.155s
sys 0m0.183s
After:
real 0m2.781s
user 0m1.826s
sys 0m0.136s
