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.
