Currently use parentheses, e.g. ":(icase,literal)path", but they do
not play well with unix shells because they have special meaning and
we need to quote them. Allow an alternate syntax ":q/icase,literal/path".
Similar to ed's s/// syntax, '/' can be replaced with anything. If the
opening quote has a closing counterpart, e.g. () [] <> {}, then it'll
be quoted as such.
It may even be a good thing to kill ':(...)' syntax, which can easily
be replaced with ':q(...)'. It's unlikely that anybody is used to it
yet.
