This option was considered, too - however we would end-up with a new
library for less than a handfull of functions which I consider a waste
of both engineering and adminstrative time. AFAIK the right place would
be libcmdutils.so but I have no clue what will happen if we redirect
consumers of Solaris libcmd.so to that library which contains other
symbols, too. Solaris's and ksh93's libcmd have clean prefixes (|def*()|
and |b_*()|) but the symbols in libcmdutil.so don't have that...
