Revision: Allow @-sign in ref names

git-check-ref-format(1) explains:

 Git imposes the following rules on how references are named:

   8. They cannot contain a sequence @{.
   9. They cannot be the single character @.

An @-sign in the middle of a ref name is fine and unambiguous,
so allow it.

Noticed in the chromium/chromium/src repo:

 https://chromium.googlesource.com/chromium/src/+/refs/experimental/aarontag@chromium.org/cookie_dev_test

produces

 Cannot parse URL as a Gitiles URL

instead of showing that ref.
