treemanifest: visit directory 'foo' when given e.g. '-X foo/ba?'
For globs like 'foo/ba?', match._roots() will return 'foo'. Since
visitdir(), excludes directories in the excluded roots, it would skip
the entire foo directory. This is incorrect, since 'foo/ba?' doesn't
mean that everything in foo/ should be exluded. Note that visitdir()
is called only from the treemanifest class, so this only affects tree
manifests. Fix by adding roots to the set of excluded roots only if
there are no excluded patterns.
Since 'glob' is the default pattern type for globs, we also need to
update some -X patterns in the tests to be of 'path' type to take
advantage of the visitdir tricks. For consistency, also update the -I
patterns.
It seems a little unfortunate that 'foo' in 'hg files -X foo' is
considered a pattern because of the implied 'glob' type, but improving
that is left for another day.
