Hi,

The changelog says

    * Various git completion fixes.

I was glad that someone finally fixed the git completion, but it turns
out it's even worse.

Previous zsh (4.3.10-16) spends a lot time on completing 'git checkout' from the
project root, but at least it's quite fast on the leaf directory.

But zsh (4.3.10-17) is just way too slow. Merely 'git checkout<tab>'
inside the kernel tree would block the terminal for 3 minutes.

For example (both were tested inside a cached kernel tree), completion
inside the linux-2.6/Documentation, profiled by zprof:

version               time                       self            name
- ----------------------------------------------------------------------------
4.3.10-16   220.65     220.65     50.10%    0.19  0.19  0.04%  _git-checkout
4.3.10-17   162868.15  162868.15  99.87%    0.17  0.17  0.00%  _git-checkout

Full profile result was attached.

Regards,
Kanru
