`quicklisp/local-projects` being a symlink doesn't work

[phmarek]

My quicklisp/local-projects is a symlink to a different directory hierarchy; ql doesn't support that:

(ql:list-local-projects)
(#P"/home/...my-local-projects/drakmadrakma.asd" ...)

Ie. there's a directory separator missing between the source directory and the asd file.

After removing the system-index.txt it works again.

My guess is that a QL directory shared between Windows and Linux doesn't work -- Windows will use #\\ in the path names, which then won't work with the linux installation any more -- but the linux side doesn't detect the "bad" names, just ignores them.
