When parse_exclude_pattern detects EXC_FLAG_MUSTBEDIR, it sets
patternlen _not_ to include the trailing slash and expects the caller
to trim it. Of the two callers, add_exclude() does, parse_attr_line()
does not.
Because of that, after parse_attr_line() returns, we may have pattern
"foo/" but its length is reported 3. Some functions do not care about
patternlen and will see the pattern as "foo/" while others may see it
as "foo". This patch makes patternlen reflect the true length of
pattern.
This is a bandage patch that's required for the next patch to pass the
test suite as that patch will rely on patternlen's correctness. The
true fix comes in the patch after the next one.
