Comment (by thomie):
I would maybe prefer separate warnings, such that even for a single
redundant clause, the warning message doesn't have to mention two
different line numbers (one for the location of the whole match, and one
for the location of the redundant clause).
I don't know if there is precedent for multiple line numbers in a warning
message.
Either way is fine though.
