1827 * allows to end the expansion. Possibly too lax. See the note by
1828 * case RleDelta. BTW, MS's documentation implies that a correct RLE8
1829 * bitmap should end with RleEnd, but on the other hand, software exists
1830 * that produces ones that don't and Windows 3.1 doesn't complain a bit
1831 * about it.
1832 *
1833 * (No) apologies for my English spelling. [Emacs users: c-indent-level=4].
