[PATCH 00/11] completion: path completion improvements: speedup and quoted paths

So, the highlights of this patch series are:

  - At the top of the worktree in linux.git with over 62k files the time
    needed for 'git rm <TAB>' goes down from 2.15s to 0.052s.

  - Same place, uniquely completing Makefile with 'git rm Mak<TAB>' goes
    down from 2.16s to 0.033s.

  - Completing paths containing escaped or quoted characters (except
    newline) will work properly, and won't fall back to Bash's filename
    completion, e.g. git add File\\w<TAB>' will list
    'File\with\backslashes.c', but not the corresponding ignored object
    file.

Well, at least it appears to be working for me, but dealing with quoting especially is nuts. If someone knows simpler ways to remove escaping and quoting than in the functions added in patches 5 and 10, then please, I would really love to learn something :)

Someone using ZSH regularly should have a look and test it.
