quoted tilde loses its quotation when path has spaces

[Radu Cristescu]

Make a path with spaces in the name:

mkdir -p "~/d 1/d 2"

Attempt to autocomplete this path:

ls -l \~/<TAB>

Expected result: ls -l \~/d\ 1
Actual result: ls -l ~/d\ 1

ls -l "~/"<TAB>

Expected result: ls -l \~/d\ 1
Actual result: ls -l ~/d\ 1

I found this out by accidentally quoting the tilde and then trying to remove it in a safe way (i.e. without deleting my home directory by accident).

I'm using Ubuntu 17.10 amd64.
