[Tailor] patch-name-format empty was not working
Changeset [1359] has not fixed it.
Please don't add the revision number, if the user wand to leave empty it.
Examples for no patchname:
patch-name-format =
patch-name-format = ""
The empty string "" is more understandable as a blank space after the '='.
This example is more for internal interestings, it set default patchname:
patch-name-format = None
All other values, set user specifics.
Tested for Monotone and Subversion. All others have similar code style,
so that should work in all repositories.
