* * eval.c (dwim_loc): Support indexing using a list of positions,Kaz Kylheku2014-07-021-70/+83
| | | | | | | | | | | | | | | such as obtained by the where function. * lib.c (replace_list, replace_str, replace_vec): Allow the from argument to be a list of index positions, possibly empty. * txr.1: Condensed syntactic descriptions under dwim operator. Range Indexing section no longer says that the value nil can be used as either endpoint of a range. This will not work any longer since a "from" value of nil looks like an empty list of indexes. Documented new behavior under replace, and shortened documentation for replace-list, replace-str and replace-vec.
