context: make repo[<filtered binary nodeid>] match node
If you pass in a binary nodeid of a filtered node to repo.__getitem__,
it would run through this code:
try:
self._node = changeid
self._rev = repo.changelog.rev(changeid)
return
except error.FilteredLookupError:
raise
except LookupError:
pass
However, repo.changelog.rev() would raise a FilteredLookupError, not
FilteredRepoLookupError. Instead, we would hit the "except
LookupError" and continue, trying to interpret the nodeid as a
bookmark etc. The end result would be an error like this:
abort: unknown revision 'ddadbd7c40ef8b8ad6d0d01a7a842092fc431798'!
After this patch, it would instead be:
abort: 00changelog.i@ddadbd7c40ef8b8ad6d0d01a7a842092fc431798: filtered node!
This only happens when we get a binary nodeid, which means it's not
string directly from the user, so it would be a programming error if
it happened. It's therefore a little hard to test (I checked
test-context.py, but it doesn't use obsmarkers).
It looks like this has been wrong ever since dc25ed84bee8 (changectx:
issue a FilteredRepoLookupError when applicable, 2014-10-15).

This test checks that:
- custom patch commands with arguments actually work
- patch code does not try to add weird arguments like
--binary when custom patch commands are used. For instance
--binary is added by default under win32.
check custom patch options are honored
