match: adding support for matching files inside a directory

This adds a new "rootfilesin" matcher type which matches files inside a
directory, but not any subdirectories (so it matches non-recursively).
This has the "root" prefix per foozy's plan for other matchers (rootglob,
rootpath, cwdre, etc.).

 To use a plain path name without any pattern matching, start it with
 ``path:``. These path names must completely match starting at the
-current repository root.
+current repository root, and when the path points to a directory, it is matched
+recursively. To match all files in a directory non-recursively (not including
+any files in subdirectories), ``rootfilesin:`` can be used, specifying an
+absolute path (relative to the repository root).
 
 To use an extended glob, start a name with ``glob:``. Globs are rooted
 at the current directory; a glob such as ``*.c`` will only match files

 All patterns, except for ``glob:`` specified in command line (not for
 ``-I`` or ``-X`` options), can match also against directories: files
 under matched directories are treated as matched.
+For ``-I`` and ``-X`` options, ``glob:`` will match directories recursively.
 
 Plain examples::
