Previously, fetch's "--tags" option was considered equivalent to
specifying the refspec "refs/tags/*:refs/tags/*" on the command line;
in particular, it caused the remote.<name>.refspec configuration to be
ignored.
But it is not very useful to fetch tags without also fetching other
references, whereas it *is* quite useful to be able to fetch tags *in
addition to* other references. So change the semantics of this option
to do the latter.
If a user wants to fetch *only* tags, then it is still possible to
specifying an explicit refspec:
git fetch <remote> 'refs/tags/*:refs/tags/*'
Please note that the documentation prior to 1.8.0.3 was ambiguous
about this aspect of "fetch --tags" behavior. Commit
f0cb2f137c 2012-12-14 fetch --tags: clarify documentation
made the documentation match the old behavior. This commit changes
the documentation to match the new behavior.

- This is a short-hand for giving `refs/tags/*:refs/tags/*`
- refspec from the command line, to ask all tags to be fetched
- and stored locally. Because this acts as an explicit
- refspec, the default refspecs (configured with the
- remote.$name.fetch variable) are overridden and not used.
+ Request that all tags be fetched from the remote in addition
