This is indeed what happens with identical entries.  But that's also a
reason not to use such identical entries: imagine a user who is
presented with the above list--how would she decide which one to
select to read about LFN?

So it's better to disambiguate the entries by adding some text to
those of them which do not describe the variable in general, but
rather mention how does it affect subtle aspects of this or that
library function.  That is, it's better to leave "@vindex LFN" in
_use_lfn.txh only, and do something like the following in the other
files:

  @vindex LFN AT r{ environment variable, and file-name globbing}
  @vindex LFN AT r{ environment variable, how to disable at startup}

etc.  This surely requires more creative work, but it improves a lot
on the efficiency of index searches, both in the on-line and in the
printed manuals.
