Function df_name_compare

tree.c:128–152

* df_name_compare() is identical to base_name_compare(), except it * compares conflicting directory/file entries as equal. Note that * while a directory name compares as equal to a regular file, they * then individually compare _differently_ to a filename that has * a dot after the basename (because '\0' < '.' < '/'). * * This is used by routines that want to traverse the git namespace * bu

 * but then handle conflicting entries together when possible.
