966	srfi-19 does not recognise the first item in abbreviation vectors for any language	Christian Kellermann	Kon Lovett	"locale-find-string from does not recognise the first elements as hits due to an off-by-1. Therefore ""Sun"", ""Sunday"" are not recognized.

However LOCALE-ABRV-MONTHS and LOCALE-LONG months work, since they contain a #f slot at index 0.

I am not sure which form is intended. By the code I guess the #f slot for weekdays is missing, or the fx< test in locale-find-string should read fx<=.

This affects scan-date's ~a format directive.

Example:

{{{
#;6>  (scan-date ""Mon, 12 Jan 2014 03:46:09 +0100"" ""~a, ~d ~b ~Y ~H:~M:~S ~z"")
#,(date 0 9 46 3 12 1 2014 3600 CET #f #f #f #f)
#;7>  (scan-date ""Sun, 12 Jan 2014 03:46:09 +0100"" ""~a, ~d ~b ~Y ~H:~M:~S ~z"")

Error: (string->date) bad date template - invalid string for indexer: ""Sun""
