Deleting a directory with the same name as a shortcut deletes everything in CWD

[Oskar Skog]

Deleting a directory with the same name as a shortcut deletes everything
in the current working directory.

Tested on:
CYGWIN_NT-10.0-19044 3.3.5-341.x86_64 2022-05-13 12:27 UTC x86_64 Cygwin
CYGWIN_NT-10.0-22000 3.3.5-341.x86_64 2022-05-13 12:27 UTC x86_64 Cygwin

Script to reproduce the bug (also in the tar):

#!/bin/bash
echo 'EVERY FILE IN THE CURRENT WORKING DIRECTORY WILL BE DELETED!'
read -p "Enter 'sure' to continue: " var
echo $var | grep -q sure || exit 1

do_stuff ()
{
     mkdir foo
     touch Foo.lnk
     if [ -d foo ]; then
         rm -rf foo
     fi
}
do_stuff
do_stuff
# All files in the current working directory are now GONE!
