cd command auto-completion with spaces in path

[wiebecommajonas]

Summary

The :cd command seems to be tripped up by spaces in the path. The auto-completion stops working and the current behavior should be changed. Auto-completed directories should be pasted either with escaped spaces or with " surrounding the whole path. I do not know if this affects other commands.

Reproduction Steps

I tried this:

mkdir a\ b
hx .

Inside hx:
:cd a<tab> works and shows directory a b.
Selecting this pastes :cd a b into the command line.

I expected this to happen:

I expected the command to read :cd a\ b or :cd "a b" after selecting the auto-completion item.

Instead, this happened:

I got the error pasted in the log section below.

Additionally the auto completion stops working after I encounter a directory containing a space (even when I type it manually with \ for spaces).

Mostly a duplicate of #4266. Also see #4316, #4587.

There's a remaining edge-case where :cd a\<tab> produces an incorrect result. I have some local changes that fix this that I'll push.
