Today I noticed that when using emacs to view the nano.info file, the
*note after an mdash does get a "see" before the crosslink.  Would it
be possible to make also 'info' consider an mdash (plus possible space)
equivalent to an opening parenthesis and thus produce a "see" after it
when 'hide-note-references=On'?


By the way, in the last paragraph of 'info texinfo cross @p' there are:
