So you could only add this at another place where pager_in_use is not yet
used (e.g. start of main or some other initialization method).
I did not want to put it at the beginning of main or another function.
After adding GIT_PAGER_IN_USE I thought it would make sense to remove
pager_in_use because there were only two parts of code using
pager_in_use:

and
