[Nasal-cvs] code.c codegen.c nasal.h

[Andy Ross]

Update of /home/nasal-cvs/nasal/src
In directory purr:/tmp/cvs-serv4483

Modified Files:
	code.c codegen.c nasal.h 
Log Message:
Remove stale extra arguments to naMod{Un}Lock() in code.c (why wasn't
gcc warning about this?).

Remove a dead function (no longer used after the tail recursion
removal) in codegen.c (about which gcc *was* warning, bully for it).

Clean up some of the docs in nasal.h to hopefully make the behavior
and requirements of the mod lock clearer.
