* lang/python/pyme/core.py (Data._error_check): Add
'gpgme_data_get_file_name' to the list of functions not returning an
error code.
* lang/python/tests/Makefile.am (pytests): Add new tests.
* lang/python/tests/support.py (verbose): New variable.
* lang/python/tests/t-data.py: Test setting and getting the filename.
* lang/python/tests/t-encrypt-large.py: New file.
* lang/python/tests/t-file-name.py: Likewise.
* lang/python/tests/t-trustlist.py: Likewise.
