Very nice. Thank you very much.
Wasn't there also a mention of the frontier pattern  being, hmmm, officially official?
Ah, yes, in readme.html, under Changes since Lua 5.1, Libraries:
• frontier patterns
It's also documented now in manual.html, under 6.4.1 - Patterns:
• %f[set], a frontier pattern; such item matches an empty string at any position such that the next character belongs to set and the previous character does not belong toset. The set set is interpreted as previously described. The beggining and the end of the subject are handled as if they were the character '\0'.
