debugignore: normalize the file before testing dirstate._ignore()
With an ignore pattern containing a '/' and a Windows style path containing '\',
status was properly ignoring the file, but debugignore was stating that it
wasn't ignored.
check-code: add rule to detect usage of external diff via extdiff
This rule detects "hg extdiff" invocation without -p/--program and
-o/--option.
This patch specifies "-p diff" explicitly in test-extdiff.t to avoid
false positive matching.
