small help bug

[Allin C. <cot...@wf...>]

"help variables" produces some information, at the foot of which 
it says:

See `show functions`, `functions`, `gnuplot-defined variables`, 
`macros`.

However:

gnuplot> help gnuplot-defined variables
Sorry, no help for 'gnuplot-defined variables variables'

Plain "help gnuplot-defined" works OK.
