patch.internalpatch: add a default value for prefix

Rev 60c279ab7bd3 adding a parameter here. This breaks third-party extensions
like crecord and also makes the issue fairly hard to fix on the extension's
side if it wants to retain compatibility across Mercurial versions -- in old
versions, the positional argument will be passed into the next unknown
argument, which is 'files'.

The patch also undoes a change to the record extension that is no longer
necessary.
