phabsend: detect patch change with larger context

Previously phabsend has an optimization that will skip uploading a diff if
the patch (with context line number = 1) remains unchanged. That could be
confusing:

  Aug 24 15:52:28 <martinvonz> phillco: something is wrong with phabricator'your patches/
  Aug 24 15:52:45 <martinvonz> ... with phabricator's view of your patches again
  Aug 24 15:53:38 <martinvonz> if i phabread D388 and then D399, i get a version of filemerge.py with "a, b, c" somewhere on line 344, which is not what phabricator shows for D399
  Aug 24 15:53:51 <martinvonz> junw: maybe that's more for you ^

Fix that by checking context with 32767 lines, which is the same as what
will be actually sent.
