        [nroff]: Work around malicious non-compliance with POSIX.
 
        * src/roff/nroff/nroff.sh: We can use POSIX shell parameter
-       substitution only if the shell supports it, but it's a hard
-       feature to test for within a shell script because non-conforming
-       shells reject it as bad syntax, aborting interpretation of the
-       script.  Use the error return status of `unset` applied to a
-       nonexistent variable as a proxy.  If the shell is thus adjudged
-       as lousy, use a cruder method of obtaining the basename of the
-       script, and refuse to process option clusters, because we need
-       parameter substitution to handle them.

        the system lacks a grep conforming to POSIX Issue 4 (1994).
