 /***************************************************
- Wrapper for str_list_make() to restore the s3 behavior.
- In samba 3.2 passing NULL or an empty string returned NULL.
-
- In master, it now returns a list of length 1 with the first string set
- to NULL (an empty list)
+ str_list_make, v3 version. The v4 version does not
+ look at quoted strings with embedded blanks, so
+ do NOT merge this function please!
