[PATCH] Fix broken VCS_Info in 5.7

[PATCH] Fix broken VCS_Info in 5.7

[dana]

A bunch of Arch users are reporting that VCS_Info is broken:

  https://bugs.archlinux.org/task/61533

To replicate it you just need to run vcs_info outside of a repo:

  % zsh -f
  % autoload -Uz vcs_info
  % vcs_info
  VCS_INFO_detect_p4:79: maximum nested function level reached; increase FUNCNEST?

This is apparently due to workers/43618, which introduced a function-def guard
to a function that wants to redefine itself. Just taking that back out seems
to fix it.

Wish they'd mentioned it to #zsh an hour or two ago :(
