Faulty understanding

[John Francis Lee]

Hello,

I'm trying to start a mercurial repository for some legislation.

I make a directory, and cd into it
run "hg init"
copy the legislation into the directory,
  2 files
run "hg commit", mercurial claims that "nothing has changed"
copy a changed version over the first version,
  2 differnet files with the same names
tun "hg commit" again, but mercurial claims that "nothing has changed"

But everything has changed.
So I must not understand how this works at all.

If I do the above steps but do the initial copy before the init, the 
result is the same.

Can anyone help me?
Thanks in advance.
