43879: vcs_info git: Fix fatal error in VCS_INFO_git_getbranch in corner case
Before this commit, the following use-case: git checkout foo^ git show foo | git am would result in a fatal error, with vcs_info_msg_N_ not set: VCS_INFO_git_getbranch:18: no such file or directory: .git/rebase-apply/onto Now they are set correctly, and HEAD's commit hash is used.
