 Actually, we currently only support a date. The cvs co -r option has the
following syntax: -r tag[:date] - so we currently always interpret the version
as a date, since we put a : in front of it.

 The :date extension is only valid when the tag is not a tag but a branch. If
the tag is empty, it refers to the trunk.

 AFAICS, the -D option is completely equivalent to -r :date .

 I applied just the third patch of this series and could build expect successfully.


 That said, I think the current behaviour is ridiculous, so perhaps the : should
be removed from the -r handling. The : can be added explicitly in the version
number - but then the directory name of expect will be
expect-_2014-05-02 which is also a bit weird...

 Note that this won't work, since the space will be interpreted as a tag name.
It should be

	select="-r :\"${rev}\""

and remove the quotes from where ${select} is used.
