Regex warning with grep 3.8

[S-Rafael]

Running btex prints the following warning:

grep: warning: stray \ before d

Steps to reproduce:

1. Create a minimal tex file:

\documentclass{article}
\begin{document}
Lorem ipsum...
\end{document}

and save it as test.tex.
2. Run btex test.tex.

What happens

The warning mentioned above appears on the command line, before any latex compiler output.

What should happen

No warning.

Version info

Happens on the latest btex from master. Running grep -V prints

grep (GNU grep) 3.8

Will have a look at the script after upgrading grep.

Haven't seen this here. grep-3.8 is still on unstable status on Gentoo: https://packages.gentoo.org/packages/sys-apps/grep
