I have a strong preference for teating whether functionality is
available, rather than testing version numbers or strings.  Not all
shells that support "set -o tabcomplete" will set $KSH_VERSION,
whereas code that says "if 'set -o tabcomplete' works then do 'set -o
tabcomplete'" will always do the right thing.
