I mentioned it in the cover letter, but that information should have
been here in this patch.  Sorry about that.

It all started out with utils/check-package telling me I used $DAEMON
wrong.  While changing that I ended up with a final comment from it
that said I should also "run shellcheck and fix the warnings".

It in turn had several grievances which I took one by one.  In this one
I used the same construct as in package/smcroute/S41smcroute to work
around a warning about using `$?` instead of using an `if cmd; then ...`

Shellcheck pointed out this section had four spaces indent instead of
the eight (tab) used for the rest of the script.  Iirc from the "own
code coding style" discussions C and shell script should follow the
same style, but I may very well be wrong here.
