Hello Vincent, on the subject of TeX runs, I noticed that TeX will
always be run each time texi2dvi is run, in the "run_makeinfo"
function, in order to check if texinfo.tex is new enough to support
macro expansion. If TeX was slow enough that an extra run was a
problem, we could look into merging these two tests somehow: I don't
think it matters though.
