During an ongoing interactive rebase __git_ps1() finds out the name of the rebased branch by executing the '$(cat .git/rebase-merge/head-name)' command substitution. That is not quite the most efficient way to read a single line single word file, because it imposes the overhead of fork()ing a subshell and fork()+exec()ing 'cat'. Use the 'read' bash builtin instead to avoid that overhead.
