Not user-driven. But the prefix part is :(literal)-applied. :(glob) is
currently implemented this way, using nowildcard_len as you mentioned.
:(icase) is more complicated and does not follow yet.

Yeah, that simplifies things. Supporting applying magic over just
parts of the pathspec pattern sounds complex. Just a small
modification. That rev-parse needs to look at "$1" as well. If
:(literal) is already specified, glob quoting will backfire. The user
script can deal with that, but it's harder (e.g. parsing magic from
scripts and deal with magic combination) than letting rev-parse does
I've done some form of this already, for supporting add--interactive.
git-add prefixes the pathspec but keeps all the magic in place, before
passing pathspec to add--interactive. But I missed the quoting point
you mentioned above. I probably need de-quoting the prefix as well.
Many optimizations stop short at the sign of any glob symbols,
including backslash. This could be a new task for wildmatch.
