Show error output from failed helpers
Usually, when the pager or the editor fail and return a non-zero
exit status, they display a message on the standard error output.
We might also try to redirect this output to show_mesage() but
it might not fit as a whole, so, given the relative rareness
of this situation, this slight inconsistency shouldn't be much
of an issue.
It'd also be possible to redirect the output to run_pager() but
in doing so, we might make the problem recursive.
