[docs] [issue12706] timeout sentinel in ftplib and poplib documentation

Greg added the comment: In the definition of FTP.connect(), I've changed the code to actually use None as a lack-of-explicit-timeout sentinel instead of -999. For FTP and FTP_TLS, I've changed the documentation to reflect what the code is doing. ---------- keywords: +patch nosy: +εσχατοκυριος Added file: http://bugs.python.org/file35524/patch.patch _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue12706> _______________________________________
