[pacman-dev] [PATCH 1/2] makepkg: Bazaar VCS support.

This patch adds Bazaar VCS support to makepkg. 

Fragments can be any bzr revision spec. eg:

http://example.com/project/#revno:62

or just 

http://example.com/project/#62

For more info, see `bzr help revisionspec`.

Writing a pkgver func is easy with `bzr version-info`, eg:

pkgver() {
  cd $srcdir/$pkgname
  bzr version-info --custom --template="{revno}\n"
}
