Right.  But other projects I've worked with often always build the tests
even if they don't run them.  But I can see arguments against doing
that, too.

Agreed.

I pushed a fix just now which makes all the tests pass for me on
GNU/Linux.  If that doesn't also fix the Git tests for you on Windows,
then I'm not sure what else could be wrong.

As for Mercurial, I can implement the temporary file thing again, but
I'd like to know about line endings first.

If you do 'hg init' in a temporary directory, 'echo foo >bar', put a
commit message containing DOS line breaks in a temporary file, and do
'hg commit bar --logfile=temp', does the commit message that gets
recorded look correct?

With Git we have to switch back to Unix line endings while writing out
the temporary file because Git expects that; I would assume Mercurial
does not, but I'm not sure.
