[Texmacs-dev] A \udots suggestion

[bump]

TeXmacs defines \udots in exported latex by:

\newcommand{\udots}{{\mbox{\rotatebox[origin=c]{90}{$\ddots$}}}}

It seems unnecessary to do this. For example xdvi complains
that rotation is not supported, and the rotated dots are not
displayed correctly.

Why not just imitate the plain tex definition of ddots:

\newcommand{\udots}{\mathinner{\mskip1mu\raise1pt\vbox{\kern7pt\hbox{.}}
  \mskip2mu\raise4pt\hbox{.}\mskip2mu\raise7pt\hbox{.}\mskip1mu}}

This works perfectly well and saves loading graphicx.
