This substitution only happens the first time Lua sets the path
(either from LUA_PATH or from the default from luaconf). If you
set the path by other means, you can avoid the problem. You may
try something like this:

  bin\lua -e "package.path='/Lua/!me/zbs/lualibs/?/?.lua'" -e "require'foo'"


(To fix this problem, maybe we should use some kind of escape. Your
particular user needed an '!' in the path, but other users may need
a '?' or even a ';'; all are valid characters in path names.)
