In both of these commands entering a non-trivial pathspec is both 
undocumented and hard to do: look at the interactive form, it calls 
read-file-name with MUSTMATCH t. In other words, it doesn't let you 
input interactively anything that's not an existing file name.

I don't see how we'd keep supporting them in these two particular 
commands without keeping bugs similar to this one unfixed (e.g. 'M-x 
vc-delete-file test[56].xx' where test[56].xx is an existing filename).

AFAICS, they're working purely by accident. That's not to say we can't 
introduce new versions of these commands that would accept pathspecs (or 
do it with C-u, etc).
