match: remove support for exact matching from main matcher class
Exact matching is now handled by the exactmatcher class.
We can safely remove _files from the __repr__() implementation,
because even though the field is set, the patternspat field is enough
for the representation to be unambiguous (which was not the case when
the matcher could handle exact matches).
