fetch: limit shared symref check only for local branches
This check was introduced in 8ee5d73 (Fix fetch/pull when run without --update-head-ok, 2008-10-13) in order to protect against replacing the ref of the active branch by mistake, for example by running git fetch origin master:master. It was later extended in 8bc1f39 (fetch: protect branches checked out in all worktrees, 2021-12-01) to scan all worktrees. This operation is very expensive (takes about 30s in my repository) when there are many tags or branches, and it is executed on every fetch, even if no local heads are updated at all. Limit it to protect only refs/heads/* to improve fetch performance. Signed-off-by: Orgad Shaneh <orgads@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
