sqrt troubles with eqn

[andlabs]

Hello. I noticed that a previous bug report by someone else talked about the
same situation, but I did not like the fix.

DESCRIPTION OF INCORRECT BEHAVIOUR: 
sqrt function in EQN seems to behave badly 

SUGGESTED FIX [optional]:

Hmm, the PS output looks fine -- eqn has no other possibility than to 
scale the right whole square root glyph, with the result that it looks 
far too fat.  Only if you use the -Tdvi device you get a decent 
looking output because the used TeX font has square root glyphs for 
different sizes. 

A completely different problem is that your attached PDF output is 
completely broken.  Using ps2pdf which comes with gs 8.51, I get a 
correctly created PDF.

For -Tdvi, I was not able to find a standalone DVI to PostScript converter,
and the only to DVI to PDF converters required a non-standalone library
called kpathsea. I didn't want to mess around with all that stuff, and I
didn't want to install TeX. I just want to have square root working
correctly: it seems as if eqn is giving zero width to the radical sign
(perhaps with \z\(sr or something else) and the upper bar (\z\(rn). I am
running the same version of groff on an Intel-based iMac with Mac OS X
10.4.10.

Thanks!
