[PATCH v2 0/4] Improve hideRefs when used with namespaces

This is a first set of patches improving documentation and behavior of the transfer.hideRefs feature as discussed in [1]. In particular, hideRefs is changed to generally match stripped refs by default and match full refs when prefixed with "^". The documentation is updated accordingly. Basic tests are added.

Changes since v1:

* Improvements in the code for denying pushing hidden refs.
* Simplification of the tests as suggested by Eric.
* New tests for the code for denying pushing hidden refs.
* Comments.
