• Use constant for exit code 23,
• Move manpage changes from top.xs to top.1,
• Proper error handling in find_pid().

@cem I'd appreciate if you could get this committed for me. I guess it needs to be properly MFCed so it gets into 11.2, and given that timeline is tight and I'm not very familiar with the process, it'll be better to get it done right from the first attempt.

Hey, either way is fine as long as it's gets committed!
Of course It's more pleasant to commit on my own, but it's not a big deal.

Thanks for fixing that! You could have added me (maintainer) to reviewers though.
Also, what's the reason to bump PORTREVISION?

Do you want to submit a PR to qutebrowser to update https://github.com/qutebrowser/qutebrowser/blob/master/doc/install.asciidoc accordingly as well? Alternatively, tell me what to add there, and I'll do so ;)

Uh, looks like I've hijacked this by https://reviews.freebsd.org/D13113 (which I committed already). Just found this one while searching for the qt-pywebengine revision. :\
Really sorry about that.
