Log Message:
apropos(1): improve error handling in edge cases

Patch from RVP on NetBSD-Users, with an additional comment tweak by me.
Summary from RVP:

1. Ignore SIGPIPE so that we're not killed in the middle of some
   DB operation by a botched $PAGER:

$ env PAGER=/non-existent apropos -p ...

2. Return proper exit status in case of write errors:

$ apropos ... >/dev/full || echo fail
