Really? Very interesting.
I assume that it’s not reproducible with the version of bash that ships with 
10.6.8 however?

Not at all.  I keep my history for a long time and have an arbitrarily large 
HISTSIZE. However, after the recent Yosemite upgrade, histories were truncated, 
so it’s relatively empty and nowhere near the level of HISTFILESIZE after the 
20 or so returns that I enter reproduce it (and I’m not sure that just hitting 
enter even puts anything in the history).

Here are the details you wanted:
graham@zebedee:~$ set | grep HIST
HISTFILE=/Users/graham/.bash_history
HISTFILESIZE=500000
HISTSIZE=500000
graham@zebedee:~$ wc -l $HISTFILE
      21 /Users/graham/.bash_history
