[PATCH 2/2] _mkdir: Honour the 'command' and 'builtin' precommand modifiers.

[Daniel Shahaf <d.s@daniel.shahaf.name>]

---
Hi,

This patch implements the "once a way is found out" comment that it removes.

It works correctly on linux:

% mkdir <TAB>
DEBUG: variant=gnu
% zmodload zsh/files
% mkdir <TAB>
DEBUG: variant=zsh

... but it would be good if someone could confirm that it still works on
$OSTYPE == (freebsd|dragonfly)* as well: the code special-cases those
$OSTYPE's.

Thanks,

Daniel
