Unfortunately lstrip isn't suitable for me, but looking it up on Google
led me to LuaSrcDiet, which does pretty much what I want (...except
locals); so thanks anyway.

Runing LuaSrcDiet on pm reduces it down to 58%, which isn't bad.
Unfortunately, once this is bolted on to the Lua interpreter source
itself, this turns into a real reduction of the resulting binary to 95%
- --- which is barely worth measuring.

Local renaming would improve that no end, as I tend to use fairly long
variable names, but I suspect what I really need is a better C cruncher.
It ought to be possible to Huffman encode all symbol names by creative
use of #define. Hmm...
