514 * returned as is, without allocating any memory. Thus additional _FREE()
515 * macros are provided. The _FREE() macros also set the pointer to NULL,

517 * 'encoding' != utf-8...
518 *
519 * Defining these macros as pure expressions looks a bit tricky but

521 * rare occasions where the comma operator comes in handy :)

523 * Note: Do NOT keep the result around when handling control back to
524 * the main Vim! The user could change 'encoding' at any time.
