Do you want to remove '-w' switch preserving '-ww' one? IMO this seems awkward.
Also, by ignoring it for now do you mean that behavior of ps with '-w'
switch would be the same as without it? I would prefer that '-w' == '-ww'.
One can remove all references to multiple 'w' switches from the man page
but leave ps itself insensitive to any number of 'w' switches
(so '-w' == '-ww' == '-www' == ...).
This also would be consistent with (for example)
