interactive: do not prompt about files given in command line
For commit and revert commands with --interactive and explicit files
given in the command line, we now skip the invite to "examine changes to
<file> ? [Ynesfdaq?]". The reason for this is that, if <file> is
specified by the user, asking for confirmation is redundant.
In patch.filterpatch(), we now use an optional "match" argument to
conditionally call the prompt() function when entering a new "header"
item. We use .exact() method to compare with files from the "header" in
order to only consider (rel)path patterns.
Add tests with glob patterns for commit and revert, to make sure we
still ask to examine files in these cases.
