Please add the underscore prefix here right away, so we don't need
that "_$1" above in __git_func_wrap().
There is still no documentation about the parameters of
__git_complete(), so...
It seems to set up completion for the command given as first argument
to invoke the completion function given as second argument, right?
But the completion function argument is optional, and if it's not
specified, its name is derived from the command name by adding an
underscore prefix (in __git_func_wrap()). So, in case of 'git', $name
becomes 'git', hence the completion function to be invoked is _git().
So far so good.

But then the wrapper function becomes _git_wrap(). Uh, oh.

... because this would then define the function _git_wrap(), which is
not good, because that's supposed to be the completion function for
the 'git wrap' command.
That's exactly why I wrote
local wrapper="__git_wrap_$1"
in my earlier post, and it was not an unnecessary change that could be
simplified away.
