Well, this is rather hack than normal using.
Because this way of using has nothing to do with the description:

 * strim - Removes leading and trailing whitespace from @s.
 * @s: The string to be stripped.
 * Returns a pointer to the first non-whitespace character in @s.

Here is the patch which removes this misunderstanding:

  * Note that the first trailing whitespace is replaced with a %NUL-terminator
