(Found on a branch from a year ago.)
- Adjust NAMEs
- MLINKS: add pfind_any.9, pfind_any_locked.9; remove old zpfind.9
- Reword the description of pfind_any() so that it doesn't imply only zombie processes are returned
- Fix a comma
- Use .Dv for the macro PRS_ZOMBIE
- Move the (logically separate) final statement to a new paragraph
- .Xr to pget(9)
Fixes: 07d78399eb79 ("pfind(9): Update to recent behavior")
