hgweb: Serve raw non-binary files as text/plain Previously these were served as application/octet-stream usually making browsers download them as files though they can be displayed inline just fine. This is useful to refer to e.g. /project/raw-file/tip/README.

allow committing a removed directory fix issue1089

notify: fix diffstat printing notify.diff() keeps line breaks in the diff buffer before calling patch.diffstat(). patch.diffstat() however adds another line break when feeding diffstat input. The added extra empty line leads to erroneous diffstat output. This fix removes the line breaks in notify.diff() and adds it back to print them.
