# pats/include/exclude cannot be represented as separate
# revset expressions as their filtering logic applies at file
- # level. For instance "-I a -X a" matches a revision touching
+ # level. For instance "-I a -X b" matches a revision touching
# "a" and "b" while "file(a) and not file(b)" does
# not. Besides, filesets are evaluated against the working
# directory.
