    Remove "keepend" and "excludenl" directives

    Remove "keepend" and "excludenl" directives

    It looks like these were never actually used correctly, and were doing
    more harm than good. "keepend" on bbString, for instance, prevented
    proper nesting of ${@python} in strings. Similarly, a balanced pair of
    { } braces inside a shell function would force the function to terminate
    early if the closing brace was on its own line.

    So far I've seen absolutely no negative consequences from removing
    these, but a bunch of positive consequences.

    Fixes openembedded#1
