They took the code from the 'file' program where it's used to say "with very long lines". There is the following comment in the source: // This code is taken from the "file" command, where it is licensed // in the "beer-ware license" :-) // Original author: <joerg@...> The limit (TEXT_MAXLINELEN 300) is commented by: /* Maximal length of a line we consider "reasonable". */ And if there's such a line, they consider the file isn't a text file. That's not "reasonable", I think. ;-) > to be necessary, maybe we should try to imagine why it is there.

I don't think so. If a line is longer than 301 bytes, conf->resultBuf = MIME_TEXT_PLAIN is not executed, that's all. The code I modified is really only used to define if the file is plain text or not. -- Laurent Dard
