use test(1) -eq and -ne to compare integers, and reduce quoting

sort and de-duplicate work tree path command line arguments
This is important in cases like 'got diff file.txt file.txt' which should only show the diff for file.txt once. suggested by kn@

Advantages over using grep are that the list of codes is validated against a list of known status codes, and that it is easier to match staged files which can display status codes in one or both of two columns. Prompted by feedback from krw@
add a -q option to tests for quiet output and use it for 'make regress'
Previous default output remains when test cases are run individually. ok tracey
fix ignores when a path is passed to 'got status'
Problem reported by semarie, who also provided initial regression test code. ok semarie
