In a couple places, coreutils.texi uses @w around (bare) long option
names. These are the ones I noticed:
621:@item @w{@kbd{--strip-trailing-slashes}}
1268:The @w{@kbd{--target-directory}} (@option{-t}) option allows the
@command{cp},
1312:operating on it. The @w{@kbd{--strip-trailing-slashes}} option enables
I'm guess the point is to avoid line breaks at the internal hyphens
(there would/should never be line breaks at leading hyphens). In which
case, a cleaner/more general approach would be
@allowcodebreaks false
Then there is no need for sprinkling @w throughout the source.
We added that in Texinfo 4.11, released 2007.
(It belatedly occurs to me that we should make @option, specifically,
always disallow line breaks at hyphens.)
