This function performs a similar function as {\em getarg()} but
prefixes the retrieved argument with the string {\em arghead} and
postfixes the argument with the string {\em argtail}. {\bf Note that}
the return value always points to allocated memory which should be
freed when no longer required.
See further {\em getarg()}.
