revlog: make pure version of _partialmatch() support 40-byte hex nodeids
Without this patch, test-histedit-arguments.t would fail when run with
--pure. It turned out to be because the pure version of
_partialmatch() does not support full 40-byte hex nodeids. When
histedit's instructions include things like "pick tip", it resolves
the "tip" revision early to a full nodeid (but plain hex nodeid
prefixes are not resolved to full nodeids). Then the nodeid (full or
not) is looked up using to a full nodeid later. This step is what
fails in pure mode. It has been failing since my c4131138eadb
(histedit: look up partial nodeid as partial nodeid, 2018-04-06). I
haven't verified, but I suspect histedit instructions like "pick <full
hex nodeid>" would have been failing before my commit too, though.
The fix is trivial: change a "< 40" to "<= 40".
