Find the last occurrence of a small string STRING1 in a large
string STRING2. Return the last substring of STRING2 beginning
with STRING1. When STRING2 does not contain STRING1, return #F.
STRING-CI-FIND-LAST performs the same function, but ignores case.
STRING-FIND-LAST-WORD (STRING-CI-FIND-LAST-WORD) differs from
STRING-FIND-LAST (STRING-CI-FIND-LAST) in that is matches only
full words, where a full word is a subsequence of characters that
is delimited on both sides by one of the following:
- the beginning of the string;
- the end of the string;
- a non-alphabetic character.
(string-find-last "a" "aaaaa") ==> "a"
(string-ci-find-last "A" "ab ac") ==> "ac"
(string-find-last "ax" "ab ac") ==> #f
(string-find-last-word "a" "ab a c") ==> "a c"
(string-find-last-word "a" "ab ac") ==> #f
