Of course, which doesn't handle commands that start with -(see 148178)
However, there's one thing that is being overlooked.
Bash and zsh's docs say command will not look at internal functions, but will
look at shell builtins and external commands. They say nothing about aliases.
Running command on zsh, ash, bash, and pdksh(ksh) all show them looking at
aliases.
The question then becomes whether this is desired behavior in maintainer
scripts, and for debhelper's use. My guess is that this isn't desired, so,
that which should be a good replacement.
