I'll definitely consider it, but I will add an explicit sf_update_header ()
for people who don't want the auto feature.

This is still a bit premature for libsndfile but I'd be very
interested in your thoughts.

I'll certainly consider it. What were you proposing? Be aware that I
am already hacking away at the internals so that while I am still
able to cope with the load, it may be better if I do the changes on
my current development tree.

BSD: A psychoactive drug, popular in the 80s, probably developed at UC
Berkeley or thereabouts. Similar in many ways to the prescription-only
medication called "System V", but infinitely more useful. (Or, at least,
more fun.) The full chemical name is "Berkeley Standard Distribution".
