[issue2577] cmd.py should track input file objects so macros with submacros can be easily written

[Richard King]

New submission from Richard King <rickbking at users.sourceforge.net>:

Add an "input" method or property that saves the current input file
object and resets the input file object; when input results in an "EOF",
the input file object stack is popped and reading continues from there.
A modified cmd.py is attached.
