Yes, that removes the high CPU load, at least for the reproducible case at hand.

I don’t know how to test that, as I don’t know what deletion of a character means in the context of a filename.

I verified that your new version works correctly with respect to file name completion.
It looks like this particular issue (30% CPU load) may be addressed. I don’t know yet whether the 100% CPU load issue is the same, as I can't reproduce it.
Do you want to check in the function above?
