Smart HTTP doesn't work yet (depends on jelmer/dulwich#295)

Tarutils Python 2.6 compatibility

It's now possible to require HTTP authentication for all of the Web
interface (not only push/pull). This isn't available from the command
line.

Note that when both whole-site password protection and Smart HTTP mode
is enabled, push is allowed by default. It can be disallowed using the
'disable_push' option.

Fix errant .split() calls that causes a TypeError

Fixed #116

The 'diff.py' module used to parse unified diff lines like

  +++ a/foo/bar /spam/eggs

as

  "/foo/bar"

i.e. stripping anything behind whitespace. This is because it tried to
recognize the part after whitespace as a commit revision id. As dulwich
never uses the latter, I simply removed that feature. Whitespace isn't
special-cased anymore now.

Split browser option into flag and option

As noted in #108, the ``--browser`` option is currently broken if no
argument is supplied. Split the argument into two: a flag
(``--browser``) indicating if a browser is to be opened and an option
(``--with-browser``) which may optionally be used to specify which
browser is to be used.

Fixes #108.

You may now optionally pass a browser name or executable to the
--browser option, which is then preferred over the default browser.

See #107.
