removing very old commits (including initial)

Manao ahoana, Hello, Bonjour,

I work on a personnal project that become a little bit bigger over the
time.
Initially, it was a single file one, and that file contained database
credentials.
Later, I splat the project and put the credentials in another untracked
file (.gitignore).
When I want to publish this project, the history contains the initial
file, with the credentials. I dont want to publish that.

It's not a problem to definitely wipe the "single file" part of history
of this project, but interesting to keep the history after the
split&untracking.

How to?
Publishing will be through gitweb.

Misaotra, Thanks, Merci.
