3 test_description="Test the svn importer's input handling routines.
5 These tests exercise the line_buffer library, but their real purpose
6 is to check the assumptions that library makes of the platform's input
7 routines. Processes engaged in bi-directional communication would
8 hang if fread or fgets is too greedy.
10 While at it, check that input of newlines and null bytes are handled
