Like $. in Perl, current_input_lineno shall hold the current line number of the current input file when all_input_lines() is running; current_input_fname shall hold the current input file name.

As I have no explicit context of the running generator (and don't want to complicate its use), these must be global variables in the jpylib (or y) name space. That may not be appropriate in some applications, e.g. if one generator is called while another one is active at the same time; in these cases, other generators must be used. Still, this may be of benefit to most use cases.
