annotate src/device.c @ 5273:799742b751c8
Accept circular lists where that is useful in #'mapcar*, #'map* and friends.
src/ChangeLog addition:
2010-09-16 Aidan Kehoe <kehoea@parhasard.net>
* fns.c (Flist_length): New, moved here from cl-extra.el, needed
by the next function.
(shortest_length_among_sequences): New.
(Fmapconcat, FmapcarX, Fmapvector, Fmapcan, Fmapc, Fmap)
(Fmap_into, Fsome, Fevery):
Use shortest_length_among_sequences() when working out how many
iterations to do, only giving circular list errors if all
arguments are circular.
