Comment 1 for bug 1330173

I created new user and bug didn't triggered. Then I copied .bashrc and bug triggered. With bisecting I found one row which destroys bash-completion for make.

.bashrc
-alias grep='grep --color=always'
+alias grep='grep --color=auto'

------
And after that, proper patch wasn't difficult.

/usr/share/bash-completion/completions/make

----
'grep grep /usr/share/bash-completion/completions/*' gives so many hits that it is possible that "grep is aliased to 'grep --color=always' " is bad idea.
