Hello,
I'm somewhat disappointed about the troff software in Plan9.
I did few initial tests with eqn(1) and in addition to the TAB problem I saw
that the root sign line and large brackets are not aligned. The attached file
shows these problems. It can be processed to PostScript with
eqn eqn.tr | troff | tr2post | psfonts > eqn.ps
(Actually on UNIX using plan9port.)
Does nobody use troff on Plan9? eqn(1) is maybe from around 1990, why had these
bugs not been fixed?
Also the font for e.g. "pi" is not as expected (like from DWB or Solaris or
groff).
Why does Plan9 troff uses other fonts than UNIX troff does?
