This starts reporting exit status of the pager back to
finish_command() and finish_command_in_signal(). But the code in
pager.c that call the finish_command*() ignore the returned value.
So, is the net result of these three patches just that the trace2
output gives the exit status of the pager, but "git" itself is not
affected otherwise (not a complaint; trying to understand the
intention) ?

I somehow find 2/3 of this change belongs to the previous step.
That is, shouldn't this new test added in the previous step without
the !MINGW prerequisite, but without the trace2 bits (i.e. the first
three added lines and the last "grep" of trace.normal), and the change
made in this step limited only to those trace2 bits?

The same comment applies to this new one added in this step.
Shouldn't the bulk of the test (i.e. under !MINGW we get killed with
signal 13) be introduced in the previous step?
