bash-completion: use POSIX character classes in regular expressions

bash uses POSIX extended regular expressions via regex(3), which does
not guarantee support for shorthand character classes. Although glibc
supports it, msys2-runtime does not.

Make sure the completion script works (hopefully) everywhere by being
more portable.
