This doesn't address the case when there are extra non-whitespace characters after the space.

taking a look...

Sorry I don't understand. If there are extra non-whitespace characters after the space, then the whitespace should NOT be removed, right? And this code should NOT remove that whitespace to my understanding.

Testing this on the board with mZ and side panels. Change works here

Previously, errors were seen when we had a space here https://asof.atl.calpoly.edu/fsw/z-panel-driver/-/commit/4072f06b08b7e8afdc9741048d6d423a46555755

Now with libproc library copied over:
Manually added space to config

Ran dev-read. There were no parsing errors or warnings on dev-read

Sorry, I read the change out of context last time. I agree this will also ignore trailing spaces on a line as written. Since we are changing behavior should we use isspace() instead to also catch horizontal tab, vertical tab, and page break?

[alexc96161]

Yeah I can agree with that
