amend: allow aborting an `amend --patch` by saving an empty file (issue5925)

This patch fixes issue5925 by allow aborting a `hg amend --patch` call by saving
an empty patch file. This is similar to aborting of `hg amend` when commit
message is empty.

Test changes demonstrate the fix.

Test the 'effect-flags' feature
