Oh, gods, I wouldn't have that at all! No, I just want it NOT to spit out not only the colour codes, but the cursor positioning codes as it seems wont to do when I do a fetch. I'm more than happy to turn coloring off (conditional on TERM would be a bonus, however it's done) on my own; in fact, I have done so, but the fetch/pull still seem to be messing up my screen, with color turned off (unless I'm not turning it off *enough*, which is entirely possible).

Well understood. Also, not asking for people to jump thru flaming hoops. Just trying to figure out how to get git to stop assuming things. (as stated, I am aware it could be my fault for not setting variables properly all the way).

That is a consideration; and one I had not thought of.

Just need to have it NOT generate ANSI codes, if requested. I'm certainly not requesting the world of terminals to be incorporated -- just some universal readability.

As far as the suggestion to use "screen", I'm not going to be starting up a screen session every time I log in. :)
