Passing the --removed option to hg log seems to exclude merge commits.  (I've
been debugging a case of a file that was removed by a bad merge, though I don't
have a simple testcase for the fact that I can't get a log of that file to show
anything about its deletion, even with --removed.)

I'd like to pass --removed as a default argument in my .hgrc, but having this
behavior of hiding merge commits means I can't.  (That said, it seems pretty bad
that it's not the default to show removal.)

A simple demonstration of the problem is attached (assuming the file attachment
works).  I would expect the "hg log --removed" to show the same output as the
"hg log".
