narrow: use diffmatcher to send only new filelogs in non-ellipses widening Before this patch, when we widen a non-ellipses narrow clone, we downloads all the filelogs matching the resulting new matcher. This is same as the ellipses case but can be improved because, we don't pull new csets in non-ellipses cases, we can only download the new added files instead of downloading all the files which matches the new matcher. So, we only download files which matches the new matcher but does not matches the old matcher. There exists a match.differencematcher() which is used here. This will lead to significant amount of speedup in extending a non-ellipses narrow copy on large repos because we will download and process only the new required filelogs. The tests changes demonstrate that we are downloading now less files. Thanks to Augie for pointing that functionality of differencematcher exists in core.

run-tests: convert the remaining os.system() call to Unicode I wasn't able to hit this path in 543a788eea2d, but I have now when I accidentally left off `--local`.

py3: partially fix pager spawning on Windows Previously, spinning up the pager crashed because the command and environment was in bytes. (See also 543a788eea2d.) Now it aborts with an invalid handle: $ HGMODULEPOLICY=py py -3 ../hg --traceback --config extensions.evolve=!
