Noted by Joseph Armbruster; patch by Jessica McKellar. The original code was 'for (;;) {...}', where ... ended with a 'return -2' statement and did not contain a 'break' or 'continue' statement. Therefore, the body of the loop is always executed once. Once upon a time there was a 'continue' in the loop, but it was removed in rev36346, committed by mwh on Wed Jul 7 17:44:12 2004. ........ r78378 | jack.diederich | 2010-02-23 11:23:30 -0600 (Tue, 23 Feb 2010) | 1 line fixup markup error ........ r78379 | jack.diederich | 2010-02-23 13:34:06 -0600 (Tue, 23 Feb 2010) | 1 line issue#6442 use in operator instead of has_key ........ r78415 | dirkjan.ochtman | 2010-02-23 22:00:52 -0600 (Tue, 23 Feb 2010) | 1 line Issue #7733: add explicit reference in asyncore docs. ........ r78559 | andrew.kuchling | 2010-03-01 13:45:21 -0600 (Mon, 01 Mar 2010) | 1 line #7637: update discussion of minidom.unlink() and garbage collection ........ r78717 | benjamin.peterson | 2010-03-05 21:13:33 -0600 (Fri, 05 Mar 2010) | 1 line settscdump is definitely an implementation detail ........ r78791 | andrew.kuchling | 2010-03-08 06:00:39 -0600 (Mon, 08 Mar 2010) | 1 line Add various items ........
