patch 7.4.1107

Browse Source 
Problem:    Vim can create a directory but not delete it.
Solution:   Add an argument to delete() to make it possible to delete a
            directory, also recursively.

delete({fname}) *delete()*
Deletes the file by the name {fname}. The result is a Number,
which is 0 if the file was deleted successfully, and non-zero
when the deletion failed.
delete({fname} [, {flags}]) *delete()*
Without {flags} or with {flags} empty: Deletes the file by the
name {fname}.
When {flags} is "d": Deletes the directory by the name
{fname}. This fails when {fname} is not empty.
When {flags} is "rf": Deletes the directory by the name
{fname} and everything in it, recursively. Be careful!
The result is a Number, which is 0 if the delete operation was
successful and -1 when the deletion failed or partly failed.
Use |remove()| to delete an item from a |List|.
To delete a line from the buffer use |:delete|. Use |:exe|
when the line number is in a variable.
