When {flags} is present it must be a string. An empty string
has no effect.

- If {flags} contains "p" then intermediate directories are
- created as necessary.
-
- If {flags} contains "D" then {name} is deleted at the end of
- the current function, as with: >
- defer delete({name}, 'd')
-<
- If {flags} contains "R" then {name} is deleted recursively at
- the end of the current function, as with: >
- defer delete({name}, 'rf')
-< Note that when {name} has more than one part and "p" is used
+ {flags} can contain these character flags:
+ "p" intermediate directories will be created as necessary
+ "D" {name} will be deleted at the end of the current
+ function, but not recursively |defer|
+ "R" {name} will be deleted recursively at the end of the
+ current function |defer|
+
+ Note that when {name} has more than one part and "p" is used
some directories may already exist. Only the first one that
is created and what it contains is scheduled to be deleted.
