Hidden Secrets of Git

This caused a bit of a headache. This is the scenario:

In repo 1:
- Edit some stuff,
- git commit,
- git tag -a,
- git push --tags.

In repo 2:
- git pull --tags,

-> The changes from the edit are visible.

This definitely isn't clear from the documentation:

--tags

All refs under $GIT_DIR/refs/tags are pushed, in addition to refspecs explicitly listed on the command line.

But very cool, nevertheless. This means it's not possible to accidentally only push the tags and not the changes associated with them.
