Message:

Handle empty changesets in Mercurial
In at least Darcs, it is possible to commit a changesets that doesn't
change anything. Such a changeset still has an author, date, log, etc.

Tailor had been just dropping these changesets, but it could be useful to
have them available -- the log messages could be important to the project,
for instance.

To preserve them, we create a .hgempty file with details of each empty
changeset and commit it.
