[PATCH 1/2] bundle: Accept prerequisites without commit messages

[Lukas Fleischer <git@cryptocrack.de>]

While explicitly stating that the commit message in a prerequisite line
is optional, we required all lines with 40 or more characters to contain
a space after the object name, bailing out if a line consisted of an
object name only. Fix this off-by-one error and only require lines with
more than 40 characters to contain the separating space.
