Detects two types of conflicts:
Example 1: Consider ref is refs/heads/foo and an existing ref refs/remotes/origin/foo/bar exists
Example 2: Consider ref is refs/heads/foo/bar and an existing ref refs/remotes/origin/foo exists

rev-parse magic :)
^{object} means the object can be any type

i love git :)
it's a great command line tool that lets you do what you need to do

not adding --no-tags when +refs/tags/*:refs/tags/* is part of the refspec... i think it would technically work the same, but would just look weird

this comment sums up the motivation nicely:
Seems pretty logical and reasonable to me that if I set fetch-depth: 0 then I clearly want everything and history matters to me and that you should not add the --no-tags parameter.

Should we do the same thing with tags? In case a force push has been made to a tag, a pull wouldn't work.

Note, this PR doesn't change that behavior but I did think about tags too.
Technically could happen for tags, however unlikely because tags typically aren't pathy and also commonly never move. Further evidence: we don't handle today and it hasn't been a problem. Same during azp, never saw issue for tag.
If it were to happen here is what the error looks like:
$ git tag pathy/name
$ git tag pathy
fatal: cannot lock ref 'refs/tags/pathy': 'refs/tags/pathy/name' exists; cannot create 'refs/tags/pathy'
Delete the repo and reclone is one way to fix. Otherwise when fetching all history, will be deleted because of git fetch origin --prune '+refs/tags/*:refs/tags/*'

do we need to error on unexpected?
