PATCH: _cd and _tilde - sorting problem

[Oliver Kiddle <opk@xxxxxxxxxxxxx>]

_tilde doesn't work very nicely when there is more than 10 directories in the directory stack and ~[+-] are completed because the list is sorted lexicographically instead of numerically so directories numbered 10-19 appear after 1 but before 2. My fix is to use -V to put the lines in an unsorted group but there may be a better way. I also had to rearrange the code before the compadd so that for ~-, the listing wasn't in reverse order. A very similar change was also necessary for _cd.

I have also added -S/ to the compadd because it is a directory that is being completed and I have put local definitions for a few variables which weren't before.
