bhyve: document signals handling and exit codes

[novel]

Summary

Update the bhyve(8) man page:

• Document powering off by sending SIGTERM signal
• Document exit codes

[wblock]

usr.sbin/bhyve/bhyve.8

302

How about a shorter version:

Exit status indicates how the VM was terminated:

310

"VM was" in these three entries is redundant and can just be eliminated entirely.

312

s/Triple/triple/ to match the other entries.

[wblock]

Oh, and remember to update .Dd. Nice to routinely run igor -R bhyve.8 and mandoc -Tlint bhyve.8 before commit, too.

[novel]

• Updated wording
• Updated .Dd

Thanks!

Thank you for review, Warren. Does that mean that I, as a ports committer, can commit it?

I usually think of accepting a review as separate from an "Approved-by", but I'll give an Approved-by for this. Remember to enter that on the commit.
