[PATCH v2 0/5] am: improve test coverage and touch up foreign patch parsing

This is a re-roll of [v1].

Previous versions:

[v1] http://thread.gmane.org/gmane.comp.version-control.git/271053

git-am is able to parse StGit and mercurial patches. However, there are no regression tests in the test suite for these patch formats, and there are some small bugs as well:

* the mercurial and stgit patch parsers does not support reading from stdin

* the mercurial patch parser parsed the patch date wrongly and git-am is thus
  unable to reconstruct the exact commit.

Some patches are based on Chris' patch series[1], which I've credited accordingly.
