test-lib: allow short options to be bundled
When debugging a test (or a set of tests), it's common to execute it with some combination of short options, such as: $ ./txxx-testname.sh -d -x -i In cases like this, CLIs usually allow the short options to be bundled in a single argument, for convenience and agility. Let's add this feature to test-lib, allowing the above command to be run as: $ ./txxx-testname.sh -dxi (or any other permutation, e.g. '-ixd') Note: Short options that require an argument can also be used in a bundle, in any position. So, for example, '-r 5 -x', '-xr 5' and '-rx 5' are all valid and equivalent. A special case would be having a bundle with more than one of such options. To keep things simple, this case is not allowed for now. This shouldn't be a major limitation, though, as the only short option that requires an argument today is '-r'. And concatenating '-r's as in '-rr 5 6' would probably not be very practical: its unbundled format would be '-r 5 -r 6', for which test-lib currently considers only the last argument. Therefore, if '-rr 5 6' were to be allowed, it would have the same effect as just typing '-r 6'. Note: the test-lib currently doesn't support '-r5', as an alternative for '-r 5', so the former is not supported in bundles as well.
