commit 37da7fb9becc0b1d35d3077e9bc3f62b741c917d

    Do not modify the buffer in `yaml-indent-line` unless necessary
    
    Calling (yaml-indent-line) for the first time on a line that the
    function already deems indented correctly results in the buffer
    getting modified even though there was nothing to modify. This is
    because the function unconditionally removes space at the beginning of
    line and then re-indents text back.
    
    Fix this by replacing the `bol` + `delete-horizontal-space` + `indent-to`
    combination with a call to `indent-line-to` which does the right
    thing.
