    rebase: update invocation of rebase dot-sourced scripts · 2f5f469b

    Due to historical reasons, the backend scriptlets for "git rebase"
    are structured a bit unusually. As originally designed,
    dot-sourcing them from "git rebase" was sufficient to invoke the
    specific backend.
    
    However, it was later discovered that some shell implementations
    (e.g. FreeBSD 9.x) misbehaved by continuing to execute statements
    following a top-level "return" rather than returning control to
    the next statement in "git rebase" after dot-sourcing the
    scriptlet. To work around this shortcoming, the whole body of
    git-rebase--$backend.sh was made into a shell function
    git_rebase__$backend, and then the very last line of the scriptlet
    called that function.
    
    A more normal architecture is for a dot-sourced scriptlet merely
    to define functions (thus acting as a function library), and for
    those functions to be called by the script doing the dot-sourcing.
    Migrate to this arrangement by moving the git_rebase__$backend
    call from the end of a scriptlet into "git rebase" itself.
    
    While at it, remove the large comment block from each scriptlet
    explaining this historic anomaly since it serves no purpose under
    the new normalized architecture in which a scriptlet is merely a
    function library.
