Tab completion of directory paths containing single quotes is broken like so:

$ mkdir -p ”a’b/c”
$ cd a\’b/ # pressing tab won’t complete the ’c’ dir

as opposed to:

$ mkdir -p ”de/f”
$ cd de/ # pressing tab here completes the ’f’ dir just fine, to ’de/f/’

I initially thought this was Bug #1485777, but the reason I’m not so sure anymore is that for me, a manually appended \’ does not disappear (unlike for the reporter of #1485777). This does however also seem like a regression back to the issue of Bug #590829.
