Equivalent to table.move for Lua 5.1

[Lorenzo Donati <lorenzodonatibz@...>]

Hi folks!

Trying to spare a little time here.

I'm writing a little library for my stuff which will make use of Lua 5.3 
table.move but should also be usable with Lua 5.1.

I could write an ad-hoc Lua 5.1-compatible fallback function, but I'd 
prefer not to waste time reinventing the wheel (and thoroughly testing 
it with all corner cases)!

So I thought that maybe a /well-tested/ /pure-Lua/ replacement for 
table.move has already been posted somewhere that I could copy-paste 
into my code.

I don't care if it is a bit slow (as long as it is not utterly 
wasteful), but it should be well tested and/or "peer-reviewed" and 
should replicate table.move semantics in the details (I wouldn't want 
unexpected differences between Lua 5.3 and Lua 5.1 scripts).

Any pointers appreciated.

Thanks!
