I merged the branch in pu into next, which I think should work, but I get
these segfaults for some commands... I tried running in gdb but even with
-g3 I only get nonsense backtraces, not sure why.

% git puhs
WARNING: You called a Git program named 'puhs', which does not exist.
Continuing under the assumption that you meant 'push'
in 2.0 seconds automatically...
zsh: segmentation fault  git puhs

% git ma
WARNING: You called a Git program named 'ma', which does not exist.
Continuing under the assumption that you meant 'am'
in 2.0 seconds automatically...
Nothing to do.

At this point I thought builtins crashed and scripts were fine, but...
% git ada
WARNING: You called a Git program named 'ada', which does not exist.
Continuing under the assumption that you meant 'add'
in 2.0 seconds automatically...
Nothing specified, nothing added.
Maybe you wanted to say 'git add .'?

However,
% git ada git.c
WARNING: You called a Git program named 'ada', which does not exist.
Continuing under the assumption that you meant 'add'
in 2.0 seconds automatically...
zsh: segmentation fault  git ada git.c
