That was a nice bit of source code archeology, but I’ve found that this format
was changed in commit 7f6d5c04a86 with the comment:
commit 7f6d5c04a869525d31e8d6e260d5195857481031
Author: Martin Mathieson <martin.r.mathie...@googlemail.com>

Don't show fragment offset as a bit field, but note number of bits used in
long text.
svn path=/trunk/; revision=22727
Note the date, that was back in 2007, so this format disappeared before
Wireshark 1.0.
Where did you get this from?
Thanks,
Jaap
