Yeah, the functions defined in the module can shadow external commands 
and the global "shell" might collide with another variable. I consider 
both bad style, however in my defence the module is meant to be used 
from simple and short shell scripts so I took some short cuts :-)

Regarding the global variable the fix is simple of course: just prefix 
the first line of the module with "local". The reason I didn't do this 
is that I don't use the "local" keyword in my shell scripts unless I 
actually need it and then the following seems out of place:

	local shell = require 'shell'

Actually I've never liked the "local m = require 'm'" idiom because I 
almost never need the flexibility of using different names for the local 
variable and the module name.
