Agree.  (However, the only use of %a I could find is in the zstyle
formats for VCS, which didn't seem to conflict.  There's definitely no
'a' in putpromptchar.  So we still have %A/%a if we think of something
else they're needed for.)

I think Oliver meant symbolic names inside the braces, like
%A{oblique}, but no matter.

I think if we created %A{4} (which BTW I would recommend requiring at
least two digits, e.g. %A{04}) then we would have to document the
existing escapes as being shorthands for the corresponding %A forms,
so yes, %u would cancel %A{04}.
