I guess the & should be a $.

Try to insist on _why_ you did this more than what it does in the commit
message.

Please, use a real email adress, not a mangled one.

I'm surprised to see this error message totally go away. The idea of the
microproject was to DWIM (do what I mean) better, but the dwim should
apply only when $directory/$file actually exists. Otherwise, the error
message should actually be raised.

This text should go between the --- and the diffstat, not at the end of
the message.

And yes, this deserves tests ;-).
