It looks like a workaround to me. Anyway, if -h is left unchanged then, I think, --help should be adjusted as well when it doesn't use an external pager.

These two commands behave differently:

git status --help 2>/dev/null | cat - git status -h 2>/dev/null | cat -

IMO, what should be changed is -h to be uniform with --help, as the it is the expected output, not an error.

Cheers, Giuseppe
