Patch to fix bug 868, and some related cleanup while I was in the area.
A tab is now taken as the end of filename if it's there, but if it isn't
(because the timestamp isn't there) we continue with the existing untruncated
line as the filename.
(r15025 from trunk plus coding-style fixes for the patch)
