PATCH: Add capability to contrib/compare_tests to handle directories


Hi,

Should not change behavior for comparing two files (expect for usage
output), and also should be POSIX compliant.

Tested on x86_64 tests logs and test directories, would be interested
in help testing on other platforms.

Ok to commit?
