pager: wrap _runcommand() no matter if stdout is redirected We've made chg utilize the common code path implemented in pager.py (by 815e1cefd082 and 493935e0327a), but the chg server does not always start with a tty. Because of this, uisetup() of the pager extension could be skipped on the chg server. Kudos given to Sean Farley for dogfooding new chg and spotting this problem.

statprof: require input file statprof has a __main__ handler that allows viewing of previously written data files. As Yuya pointed out during review, f42cd5434cc2 broke this. This patch fixes that.

tests: work around FreeBSD's unzip having slightly different output According to man 1 unzip, this unzip appeared in FreeBSD 8.0. It's what comes as /usr/bin/unzip, so we may as well cater to it since it's easy.
