Segfault while testing __git_files functions

["Benjamin R. Haskell" <zsh@xxxxxxxxxx>]

While trying to come up with a minimal "do __git_tree_files when I say 
__git_files" example, I came upon an error that gives me a reproducible 
segfault.

Attached test script can be run from `zsh -ldf`:

host% . ./git-break.zsh

It'll create a git repo, and prep it for the point where it'll break if 
you hit Tab.

Stack trace attached.  (built from rev 348d284)
