Subject: [Rd] texi2dvi / egrep issue shows (a.o.) up in R-alpha
Message-ID: <4D87D50D.60506@openanalytics.eu>

L.S.

I noticed weird tools::texi2dvi behaviour on R-alpha
when specifying an absolute path to the .tex
file.

The same phenomenon also appears to occur on
R-2.12.2, so maybe the issue is independent
of R.

I hope I did not overlook any important information.

Best,
Tobias

This is Ubuntu 10.10 with GNU grep 2.6.3 and
texi2dvi (GNU Texinfo 4.13) 1.135.

The test file is most simple:

Test document.
