form theme function reuse.

the hook_form let reuse the form but with different _validate and
_submit... but different theme function too (unless I'm missing
something).

For form reuse hook_forms is a bit smarter than defining aliases
(function that just call other functions), since you can build the
alias automatically.

form_a, form_b and form_c will actually use the same $form but with
different _validate and _submit functions... but with different theme
function too... and it doesn't make too much sense to me... unless
I'm missing some parameter...

I'd say you could alias the callback *and* the theming function... so
in the hook_form you'd decide which code each "form" (considered as
the tuple $form, _validate, _submit, theme_) have to share.
