Well, this "\r" allows to recognize when file with Windows line ending (CRLF) made it into repository... which usually is discouraged. But if you allow this, I can understand that those "\r" at the end of every line can be annoying.
A simple _workaround_ would be to create one's own extra stylesheet, with rule hiding control characters visualization (including "\r"), e.g.
.cntrl { display: none; }and stuff thys additional it in @stylesheets via gitweb config file.

Please read Documentation/SubmittingPatches if you want your work to be considered for inclusion. This is not a proper patch -- it lacks commit message (comments should be outside of it, e.g. between "---" and diffstat) and signoff.

Note that your patch beside hiding "\r" in the case when file has Windows line endings, it also hides "\r" in the case where file has _mixed_ line endings (LF mixed with CRLF, which is incorrect). Though handling that well would be quite difficult, I think...
Though esc_html gets passed whole lines, I am not sure if it always gets passed whole lines and would continue getting passed only whole lines in the future, so there should be 'g' modifier (or better 'gm' modifier to make sure that $ matches end of line not only end of string).
I think it would be better if there was an option to switch hiding "\r" on and off... though I am not sure if it can be done without incuring large performance penalty.
