'cd' and 'rmdir' and others fail to complete directory paths past the first level if the first directory contains single quotes

[Jani Uusitalo]

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.

It's not the same as #590829 after all: despite the similarities, the recipe given at #590829 does not reproduce the issue for me.

Status changed to 'Confirmed' because the bug affects multiple users.

This only affects some commands. 'cd' and 'rmdir' and 'mkdir' are affected. My guess is that it affects commands that work exclusively with directories.

[Mathew Hodson (mhodson)]

Here is another testcase that produces a similar failure.

$ mkdir "Apostrophe's a problem"
$ mkdir "Apostrophe's still a problem"
$ cd Apostrophe\'s\<tab>

It should complete or offer options, but it doesn't complete any further and doesn't offer any suggestions.

If you add on to where it should be able to complete like so:

$ cd Apostrophe\'s\ still<tab>

It does not complete even though there is only one possibility.
