create lowercase strings in lists - was: (No subject)

[Mark Devine]

Actually what I want is element 'class-map match-all cmap1' from list 1 to match 'class-map cmap1 (match-all)' or 'class-map cmap1 mark match-all done' in list 2 but not to match 'class-map cmap1'.
Each element in both lists have multiple words in them. If all the words of any element of the first list appear in any order within any element of the second list I want a match but if any of the words are missing then there is no match. There are far more elements in list 2 than in list 1.

For example the larger list could have an element 'class-map cmap2 (match any)' and I want to match that but if only 'class-map match-any' or 'class-map cmap2' appears I don't want it to match.
