The rules used by "git push" and "git fetch" to determine if a ref can or cannot be updated were inconsistent; specifically, fetching to update existing tags were allowed even though tags are supposed to be unmoving anchoring points. "git fetch" was taught to forbid updates to existing tags without the "--force" option. * ab/fetch-tags-noclobber: fetch: stop clobbering existing tags without --force fetch: document local ref updates with/without --force push doc: correct lies about how push refspecs work push doc: move mention of "tag <tag>" later in the prose push doc: remove confusing mention of remote merger fetch tests: add a test for clobbering tag behavior push tests: use spaces in interpolated string push tests: make use of unused $1 in test description fetch: change "branch" to "reference" in --force -h output
