I don't see how using "C-h v" in that case is a reasonable use case,
since the documentation is displayed right below the name of the
option.

We could perhaps have a help command that recognized names of
variables in this format, but then it shouldn't be "C-h v", IMO, since
that command talks about _variables_, whereas a name such as "Info
Hide Note References" is not a variable name.
