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.
