Yes, I think this should be made consistent with this:

@node set value
@subsection @code{@@set} and @code{@@value}
@findex value

@cindex underscores in @code{set} and @code{value}
You can use the @code{@@set} command to specify a value for a flag,
which is expanded by the @code{@@value} command.  A flag is an
identifier; for best results, use only letters and numerals in a flag
name, not @samp{-} or @samp{_}---they will work in some contexts, but
not all, due to limitations in @TeX{}.  The value is just a string of
characters, the remainder of the input line.
