Merge of r3996, r3998, r4015, r4023, r4025, r4026, r4027:

Changes log build procedure fixes:

*) using sed instead of perl
*) support <br/> in the middle of input
*) fixed "<br>" lookup (eliminates the need in " <br/>" hacks)
*) fixed maximum length for unbreakable input
*) fixed space lookup (allows a space at column 77 to break a line)
*) traling spaces removal in text CHANGES files.
