grep: fixes erroneous output of grep in forward order (issue3885)

If grep is passed a revset in forwards order via -r , say -r 0:tip
Then the output is erroneous. This patch fixes that. The output was wrong
because we deleted the last revision key in the matches and when we moved
to the next revision we didn't had this to compare the diff. So the pstates
dict was always empty and in the SequenceMatcher, to convert and empty pstate
to the states dictionary you would always insert. This patch keeps the matches
dictionary until the end of this window and clears it at once when this
window ends. This solves the above mentioned problem and also do not cause
any memory leak.
