[xorg-xinit] startx breaks if GREP_OPTIONS changes output format

Description
This was reported on the Arch Linux bugtracker but it's an upstream issue, so I'm reporting it here.
I think appeared by the xinit git tag xinit-1.3.4 . I think would've been introduced by commit http://cgit.freedesktop.org/xorg/app/xinit/commit/?id=44915d6953076849b69a017f6fc8234b0f254362 .
- tty_num=
(echo "tty" | grep -oE '[0-9]+$')
If GREP_OPTIONS has color=always set, then this uses coloured grep output, meaning $tty_num carries colour information in vtarg="vt$tty_num".
To resolve:
- tty_num=
(echo "tty" | grep -oE '[0-9]+$')
- tty_num=
(echo "tty" | grep --color=never -oE '[0-9]+$')
Some people reported a problem on the Arch Linux Forum: https://bbs.archlinux.org/viewtopic.php?id=186382
While it's not yet entirely sure that it's due to this issue I think it may well be.
An error that was posted there contains:
Command line argument number 4 contains unprintable charactersThanks
