Description

Allow admins to specify a field width like "%12p" for eg. the process name to truncate it below the 16-character maximum that the kernel imposes, and give more room to the other fields to fit into the JobID limit.

It may also be possible to have a negative field width like "%-8H" to use the last 8 characters of the short hostname instead of the first 8 (if over 8 characters long). This may have other issues, but can be useful in some cases, and would be up to the discretion of the admin.
