[ntp:hackers] Leap second support in versions prior to 4.2.6

As you might guess, questions about the leap second have been ramping
up. I found page on the support wiki (
http://support.ntp.org/bin/view/Support/ConfiguringNTP ) that says
"6.14.2. NTP Versions before 4.2.6: Pre-4.2.6 versions of ntpd evaluates
the leap second file only if the autokey feature has been enabled."
However, my testing with ntp-dev-4.2.5p172 and ntp-dev-4.2.5p200 show
that this statement is false. Both of these versions will read the leap
file if configured via the "leapfile" keyword.
I tried to look to see what versions actually do and do not support the
leapfile without autokey, but unfortunately I was stymied by the rather
abysmal source browser that bitkeeper uses. Perhaps I am just missing
something obvious about how to browse historical releases with the
browser, but it seems to me to be just about the worst browser I have
used in this regard.
Which leads me to my next question, is there any reason that we should
continue to use bitkeeper? When we adopted it, it seemed to be pretty
snazzy, but it seems to be getting fairly long in the tooth. Subversion,
Mercurial and Git all seem to be better systems these days. Is there
some feature in bitkeeper that I am missing that makes it a compelling
choice for us?
