sslutil: remove out of place comment This comment likely got orphaned as a result of refactoring in this file. It isn't providing any useful value. So delete it.

largefiles: remove additional blank line between methods in localstore According to the coding style it should be a single blank line between functions.

revset: make head() honor order of subset The ordering of 'x & head()' was broken in 6a1a4c212d50 (revset: improve head revset performance, 2014-03-13). Presumably due to other optimizations since then, undoing that change to fix the order does not slow down the simple case of "hg log -r 'head()'" mentioned in that commit. I see a small slowdown from ~0.16s to about ~0.19s with 'not 0 & head()', but I'd say it's worth it for the correct output.

revsets: use itervalues() where only values are needed I don't think there will be a noticeable speedup, but it removes an unused variable.

revsets: passing a set to baseset() is not wrong Since 69c6e9623bdc (revset: force ascending order for baseset initialized from a set, 2016-04-04), it is safe to pass a revset to a baseset.

pyflakes: use pycompat.pickles to prevent error The pyflakes in my test box complain about pickle in pycompat. mercurial/pycompat.py:17: 'pickle' imported but unused
