[PATCH 1/4] git-p4: use with statements to close files after use in patchRCSKeywords

Python with statements are used to wrap the execution of a block of code so that an object can be safely released when execution leaves the scope.

They are desirable for improving code tidyness, and to ensure that objects are properly destroyed even when exceptions are thrown.
