Tab Completion of File Paths

[Scott Morgan <blumf@...>]

The thread on getting script paths made me think of something that'd be
useful, but is possibly hard to do and certainly shouldn't be within the
standard distro: Tab completion for file functions.

e.g. you're in a REPL Lua interface and you do something like:

 > f = io.open("c:\exa<tab>
 > f = io.open("c:\example\

Same for any of the functions that take file paths.

Has anybody done this? How?
