Hi Osamu,

Thanks for following up this bug.  I confess I had forgotten about it!

Anyway, I took the liberty and implemented the following mostly-untested
patch to uscan which uses your idea and executes debian/mk-origtargz (if
it exists and is executable) instead of the system's mk-origtargz.

What do you thing?
