revlog: remove micro-optimization for looking up only nullid index_find_node() would call nt_find() before initializing the node tree. nt_find() would then return -2 unless the requested revision was the null revision. I can't imagine what scenario that is optimizing for, and doing the initialization earlier makes the code simpler and easier to follow, so that's what this patch does.

$ make install    # do a system-wide install
$ hg debuginstall # sanity-check setup
$ hg              # see help

Running without installing:

$ make local      # build for inplace usage
$ ./hg --version  # should show the latest version

See https://mercurial-scm.org/ for detailed installation instructions, platform-specific notes, and Mercurial user information.
