git-p4: add tests demonstrating spec overlay ambiguities
Introduce new tests that look more closely at overlay situations when there are conflicting files. Five of these are broken. Document the brokenness. This is a fundamental problem with how git-p4 only "borrows" a client spec. At some sync operation, a new change can contain a file which is already in the repo or explicitly deleted through another mapping. To sort this out would involve listing all the files in the client spec to find one with a higher priority. While this is not too hard for the initial import, subsequent sync operations would be very costly. Signed-off-by: Pete Wyckoff <pw@padd.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Bugs in the implementation of overlap mappings exist. If multiple depot

git-p4 can choose the wrong one. This is hard to solve without
