[PATCH] make assumed terminal width on cmd help dynamic

[Felix Zielcke]

Thanks to nyu and daChaac on IRC
By default with gfxterm loaded and gfxmode set to 640*480 help command produces 
empty lines see [0]
help command assumes a fixed width of 80 but gfxterm in 640*480 has only 77

This is a patch to fix it.
