Now the existing whitespace gets turned into a blank, the way it does in other header reformatting, and the _continuation_ws gets added at the beginning of the encoded line. ........ r88164 | r.david.murray | 2011-01-24 14:34:58 -0500 (Mon, 24 Jan 2011) | 12 lines #10960: fix 'stat' links, link to lstat from stat, general tidy of stat doc. Original patch by Michal Nowikowski, with some additions and wording fixes by me. I changed the wording from 'Performs a stat system call' to 'Performs the equivalent of a stat system call', since on Windows there are no stat/lstat system calls involved. I also extended Michal's breakout of the attributes into a list to the other paragraphs, and rearranged the order of the paragraphs in the 'stat' docs to make it flow better and put it in what I think is a more logical/useful order. ........
