The above sentence, while it may be telling a truth, feels more or
less irrelevant, especially the part that talks about TERM=msys.
Even if GitExtensions used TERM=vt100, the end result would be the
same, wouldn't it?
If you are suggesting a fix to GitExtensions to make it export
TERM=dumb like everybody else does, that would be a different
story. Mentioning "TERM=msys causes the problem" would be a very
relevant thing to do. But this patch is not that.

This on the other hand is very readable. How about rephrasing these
two like so:
Diagnostic messages received on the sideband #2 from the server side
are sent to the standard error with ANSI terminal control sequence
"\033[K" that erases to the end of line appended at the end of each
However, some programs (e.g. GitExtensions for Windows) read and
interpret and/or show the message without understanding the terminal
control sequences, resulting them to be shown to their end users.
To help these programs, squelch the control sequence when the
standard error stream is not being sent to a tty.
There are programs that drive other programs (not limited to Git)
through pty (hence satisfying isatty(2)) without interpreting the
ANSI terminal control sequences, and it is conventional for these
programs to export TERM=dumb, so and your patch still checks for
TERM=dumb to help them, which is very good.

And if you explain it like the above, I do not think this external
reference is very useful.
