Other changes in nagbar_exited:
- Remove ERROR from ELOG as it shows up as "ERROR: ERROR:"
- Make sure to reset the PID even when the process did not exit
normally.
- Use ELOG when exitcode != 0
- Remove the not found error: if nagbar is not in $PATH, exec_i3_utility
prints an error as well.
For the record, I also implemented a more complicated approach with a
new watcher data structure:
bd3aaf3a33
While writing the commit message, it occurred to me to compare
watcher->pid with *watcher->data, which fixes the problems mentioned in
that patch.
Fixes#4104
