If you're configuring a prompt, sometimes you need to be able to
include a space at the end of it. Since trailing whitespace on a line
in the file itself is a bad idea, you need some way of marking it.
That might mean quoting the string, or having a Unicode or byte escape
like \x20 that means space, or something like that. If you define that
spaces around your equals sign are insignificant, you need the same
sort of system to cope with the possibility of actual leading
whitespace, too.

Ehh... I reckon they're pretty simple. They're somewhat more powerful
than Upstart config files, and pay some complexity cost for that; but
they're a lot simpler than sysvinit "config files" (which are actually
shell scripts), especially with all the dependency handling cruft that
goes into encoded comments. Frankly, I do my best to avoid ever
touching those. I'm not sure what else to compare them against (never
used any init system other than the three just mentioned), so I don't
see systemd files as being particularly complex.
