The test you mention is ok under NetBSD /bin/sh, but fails under bash, which is strict on integer variables (an empty var is not 0). I will fix it to work in any case.
This code addresses the case where a -<n> flag and an explicit version are given (i.e. dim diff -1 dim-0-mv47). The -<n> flag produces an implicit "old" definition, so we want the explicit version to be the "new" instead of the "old", despite being formally the first arg.
