Actually I meant removing the default input (the "grep -nH -e" part)
completely, and replacing it with these commands.  So more precise
recipes are:

`M-x grep RET C-a C-k set RET'
`M-x grep RET C-a C-k echo $TERM RET'

But anyway I see that your $SHELL is "bash.exe" and $TERM is "emacs-grep".

Could you also try running grep from Bash (not from Emacs) with options
"--color=always" and "--color=auto" and see whether it outputs highlighting
sequences for both cases in a standalone shell?
