TeX really does not want to run in batch mode :( So this patch makes
it shut its hears when asked to.
Index: ChangeLog
from Akim Demaille <address@hidden>
* util/texi2dvi: More uses of the verbose function.
(run_tex): New function to factor the two tex invocations.
Move the handling of tex arguments in here to improve locallity.
Enforce the batch mode by closing its stdin.
