Package: a lot of them
I've recently set GREP_OPTIONS='--color=always' in my bashrc. I do this mainly so that I can see grep's highlighted findings even when viewing through a pipeline, such as with less. '--color=auto' won't work because it will turn off the color escapes if it's going down the pipeline, which is not what I want when I use less.
This poses a problem for a lot of scripts, which assume that text coming from their stdin is free from (color) escapes. For instance, I recently went to install postgresql-client-8.2 in Ubuntu. (I recognize that Ubuntu != Debian. However, this is also a problem in Etch that I just didn't report earlier, and I think it could be addressed in both distros.) 

> $ sudo apt-get install postgresql
>    ...

Setting up postgresql-client-8.2 (8.2.7-0ubuntu0.7.10) ...
update-alternatives: unable to make /usr/share/postgresql/8.2/man/man1/dropuser.1.gz.dpkg-tmp a symlink to /etc/alternatives/dropuser.1.gz: No such file or directory


^^^^^^^^^^^^^^^^^^^^^^^

The ^^^^ is color-escaped, which is no good for the symlinking.
I think an appropriate solution would be to unset or export GREP_OPTIONS='--color=none' in the beginning of scripts that rely on grep.

Hi,

(I do not understand why the submitter does not use
GREP_OPTIONS='--color=auto'.)

Anyway, you can break many normal program operations if you set
unreasonable value to environment variables.  This is not just
GREP_OPTION for grep but you can have fun with TAPE or TAR_OPTIONS for
tar. It is only yourself to blame.

Since submitter said "smart" to other fix method, it is best to close
this bug.

Cheers,

Osamu
