No, ${parameter:offset} and ${parameter:offset:length} are bash specific
not XSI mandated.  IIRC we already have a separate test for bash
features that won't regress on non-bash XSI shells.  Please add the test
there.  Then, the patch is ok if you have ensured that our testsuite
covers the code path (i.e., tries a short option that needs splitting
this way) or added it there, help.at would be a good place.  And tested
on one system that has a good shell and one that has a bad shell.

Thanks!
