cmd: WCMD_delete: fix /s for dirnames containing spaces, add test (try 2)

[Dan Kegel]

Move the loop body of WCMD_delete into a new function WCMD_delete_one
Recurse via that function rather than WCMD_delete
Add a test for del /s with directory names containing spaces
Fixes http://bugs.winehq.org/show_bug.cgi?id=26885

This is the non-ugly fix Alexandre was asking for in
http://www.winehq.org/pipermail/wine-devel/2011-April/089817.html

(The refactoring removed a scope, unindenting lots of code, so
reading the patch is easier if you apply it first, then do 'git diff -b'.)
