[Extra patch that may be added to the series I submitted previously]
A single 'config' object may parse multiple files, and most of the data
needed to parse a file is passed as argument to the parse() method,
except for the filename. As we're now tracking the filename on the
configreader object (that is created only when we start reading a file),
we can simply use this attribute instead of config.filename.
The config.filename attribute was only used when handling the 'include'
statement, so that's the only part of the code that needs to be adapted
to accommodate the change.
