a3b1bebb5b Fix misuse of preg_quote (#869) 
1. Variable ids can contain slashes or dots, e.g. for `${'my/var'} = 2`
   or psalm's local representation of properties or array indexes
   (I forget which)
2. preg_quote's escape character should **always** be the same as the
   pattern starting character.
   Using DIRECTORY_SEPARATOR will fail to escape '/' on windows.
