Oh my! I consider this a bug in mercurial, but I guess the problem is that
it isn't representable in the language of plain "patch". Please, everyone,
edit your ~/.hgrc and add the following two lines:

[diff]
git = True


With this,

$ chmod +x ex5.c
$ hg diff
diff --git a/src/snes/examples/tutorials/ex5.c
b/src/snes/examples/tutorials/ex5.c
old mode 100644
new mode 100755


Thanks for pointing this out.
