Escape \n line returns in .bzr-upload.revid

[Jeff Fortin Tam]

In some cases, like bzr uploading to a host that already has the files (if it was previously done with rsync for example), you may want to

echo "<email address hidden>" > .bzr-upload.revid

However this won't work, because there is a trailing line return. When you try to bzr upload, you get a bazaar internal error (asking you to file a bug report :) :

NoSuchRevision: KnitPackRepository('file:///foo/.bzr/repository/') has no revision ('<email address hidden>\n',)

Ideally, bzr-upload should strip out the \n.

[Vincent Ladeuil (vila)]

There is 'echo -n' to *not* add the '\n'.

If you're going to trick bzr-upload though, keep in mind you're on your own, I see no compelling reason to help "cheaters" trigger obscure bugs in the plugin by making their life easier ;)
