Escape backticks

[nephros]

The commands between them are actually evaluated, leading to lots of confusing help output in the log file.

Note that the behaviour is different depending on whether backticks appear between single or double quotes.

L75 is fine, log snippet:

L146 and friends are not, they are expanded to pkcon help output:

Oops, thank you very much!

Obviously I have not take a close look at the logfile for long and I regularly fail to immediately comprehend what the backticks do in shell scripts, because I do not like this ancient syntax and always use $() since the 1990s.

Yes, sure, that is what the "modern" syntax ($()) makes obvious so nicely, because most have the simplified rule in mind: Nothing is evaluated between double-quotes, except for $ followed by something, but in fact a sequence of two backticks also are.
With single quotes really nothing is evaluated between them.
