Use Term::ReadKey, if available and enabled with interactive.readkey,
to let the user answer add -p's prompts by pressing a single key.
We're not doing the same in the main 'add -i' interface because file
selection etc. may expect several characters.
Two commands take an argument: 'g' can easily cope since it'll just
offer a choice of chunks. '/' now (unconditionally, even without
readkey) offers a chance to enter a regex if none was given.

Bah; I edited the patch message after format-patch last time and
forgot to do it again. The above is the intended message that covers
'/' too. Sorry for the noise.
