ANSI sequences produced on non-ANSI terminal

Thank you for filling out a Git bug report! Please answer the following questions to help us understand your issue.

What did you do before the bug happened? (Steps to reproduce your issue)
	Logged on to a hard terminal and ran 'git status .' and
	'git pull'.

What did you expect to happen? (Expected behavior)
	I expected that colour sequences would not be output, or at least
	not hardcoded to ANSI standard.  In the case of 'pull', I expected
	that the stats would be just printed using <string>\r.

What happened instead? (Actual behavior)
	I got escape sequences that made the output unreadable.

What's different between what you expected and what actually happened?
	One produces mangled ouptut and the other doesn't.

Anything else you want to add:
	I searched google and the documentation as best I was able for
	this, but I am unable to find anywhere that will let me disable
	(or enable) colour for a particular term type.  Sometimes I'm on
	an xterm, for which this is GREAT.  Sometimes I'm on a Wyse WY60,
	for which this is sub-optimal.  My workaround is to disable colour
	completely, which is reluctantly acceptable, but it would be nice
	to say "If I'm on an xterm/aterm/urxvt/ansi terminal, enable
	colour or cursor-positioning, otherwise shut it off."  If this
	seems too much of a one-off to handle, fine, but most things that
	talk fancy to screens are kind enough to allow an opt-out based on
	terminal type. :)
