No, of course not, but lynx is doing it in several places.
But this is not one of them: the check for the title is only one
of several conditions that are ANDed.

It makes sense to have this extra check before treating the file as a
bookmark file IMO.

Even mattack says it's only a minor annoyance to him (or words to that
effect); it happens only once in a session; it's not worth changing the
program structure for, IMO.

He isn't actually annoyned with Lynx's roundabout way to detect a
bookmark file; he is only annoyned with the way it is becoming
visible.   But that happens only with -partial, and arguably, by
using -partial and starting lynx this way he's asking for it.

The "standard" way to access a bookmark file (and have it recognized
as such) is via bookmark-specific commands: 'v' as a key, or '-book'
on the command line.  If lynx sometimes recognizes a bookmark file
even if you don't do that, it is because of code additions that Fote
made because people kept asking for it.  But those work only in some
cases anyway (here: if the file in question is the "first file").

The canonical way to *start* with a bookmark file (and have it
recognized as such) is -book.  That hasn't ever been properly
generalized for starting *directly* with such a file.  But you can
still start with -book if multi-bookmarks is on - you just have to
answer a prompt then and select a bookmark with a letter (or press
return for default).

Finally, if someone just want to start lynx with that file and just
doesn't care for it being recognized as a bookmark file and being
treated specially in some ways - there's a trick possible to prevent
the special first_file recognition.  Just use some unusual form for
the starfile that doesn't get recognized; for example, instead of
   lynx ~/lynx_bookmarks.html
   lynx ~/%6Cynx_bookmarks.html
