[l2h] bib & natbib patches

[Bruce R Miller]

Hi all;
  It looks like BibTex found an even more clever place to 
break lines!  If a bibitem gets split up like this:
   \bibitem[\protect\citeauthoryear{Olver}{Olver}{1974}]{%
   Olver74}
   F.~W.~J. Olver (1974).
    ...
the $comment_mark does NOT get stripped out of the $cite_key.
Somehow the default bibliography style manages to find a proper 
entry (from aux ??; the internals.pl file gets extra entries), 
but natbib.perl does not.  
Consequently, the citation link is broken.

A fix would be to insert the line:
 $cite_key =~ s/($comment_mark\d*.*\n)?//g;
after $cite_key = &missing_braces unless ...
in sub do_real_bibitem (in latex2html, natbib.perl,
and any other bibliographic style files).

Another problem is that there's been a change to natbib.perl that
looses the authors names.  When I hacked it up last year, 
I put in:
	$short =~ s/$next_pair_pr_rx/$2/go; # Remove excess braces

That's now been changed to:
	$_ = $short;
	s/$next_pair_pr_rx//o;
	if (!($2 eq $cite_key))
	    {$short =$2; $short =~ s/$OP[^\#>]*$CP//go; }

Undoubtedly the patch is there for a good reason, but 
unfortunately, if there are NO excess braces, it assigns undef 
to $short (and $long later on).  Maybe the s/.../ could be brought
into the if(s/..//o && !($2 eq $cite_key))   ??

Thanks;
OBTW; Ross; it was great meeting you at TUG!
