That was quick.  Is this change only for tex4ht or for latex2html as well?
Can it easily be extended to latex2html?

latex2html output appears to work well.  I haven't had good
results with tex4ht, even without @var, but this appears to be
the right way of doing things, provided tex4ht works.  (I found
@math{@var{foo}\over@var{bar}} output as

<span 
class="cmti-7">foo</span>
<span 
class="cmti-7">bar</span>

and the square root operation was output as a blurry image.  It probably
depends on settings and versions.)

tex4ht still appears to get updates:

https://svn.gnu.org.ua/viewvc/tex4ht/trunk/

although I hear it has been a difficult piece of software to maintain
since the death of its original author in 2009, so problems or drawbacks
with tex4ht may not ever be resolved.
