Description

Shellcheck 2206 and 2068 have been disabled in _forgit_ignore for a very long time. The code that triggers the shellchecks was added in ce240ac before the shelllcheck action had been added. The shellceck for the lines in question got disabled in c14ce93. The commit message does not state why, but I'm guessing that this has been done simply to make the CI pass. I do not think disabling the shellchecks is necessary here. I've implemented the fixes shellcheck suggest and I could not find any issues with it.
