Subject: git fails with a broken pipe when one quits the pager
Message-ID: <YAG/vzctP4JwSp5x@zira.vinc17.org>

I had reported the following bug at
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=914896

It still occurs with Git 2.30.0.

Some git commands with a lot of output fail with a broken pipe when
one quits the pager (without going to the end of the output).

For instance, in zsh:

cventin% setopt PRINT_EXIT_VALUE
cventin% git log
zsh: broken pipe  git log
cventin% echo $?
141
cventin% 

This is annoying. And of course, I don't want to hide error messages
by default, because this would hide *real* errors.

The broken pipe is internally expected, thus should not be reported
by git.

Just to be clear: this broken pipe should be discarded only when git
uses its builtin pager feature, not with a general pipe, where the
error may be important.

For instance,

$ { git log ; echo "Exit status: $?" >&2 ; } | true

should still output

Exit status: 141

like currently.
