It's not an absolute rule. Avoid long lines where possible, but don't
jump through hoops to e.g. break long strings in assignments.

This is in PMS section 12.3.17 "Reserved commands and variables":
https://dev.gentoo.org/~ulm/pms/head/pms.html#x1-13700012.3.17

Let's add it to the devmanual as well:
