[l2h] Workarounds for two bugs (equations with white margins, and more)

[Daniel Clemente]

   Hi, I have put a web page with two patches I used to solve some bugs:
http://www.danielclemente.com/linux/l2h.html


   The patches follow: (for version 1.70, but the bugs still affect the CVS one)


Uncomplete tables (only the header is present)
------------------------------------------------

   Some tables fail to render correctly if they are coming from a LyX
document. The fix was proposed to this list but hasn't been applied to
the trunk yet.

              if (($VERBOSITY>1) && $replacements);
  

Large margin on the bottom of some equations
--------------------------------------------

  I have seen several documents all with this problem.
  This "fix" is probably a hack.

   Hoping to see them solved some day,
