bug#58199: 29.0.50; Odd "git pull" output

[Lars Ingebrigtsen]

Alternatively, if there was some way to make "git pull" not do stuff
like that in the output, that would be even simpler.  But the only thing
I find is:

       --progress
           Progress status is reported on the standard error stream by default
           when it is attached to a terminal, unless -q is specified. This
           flag forces progress status even if the standard error stream is
           not directed to a terminal.

And we don't want "-q" -- we just don't want the progress output, I
guess, and that can't be disabled separately.

But I may be missing something -- anybody know?
