Message 118429 - Python tracker

Another syntax could be attached to if-else and try-except.  Given:

    if ...:
        <block 1>
    else:
        <block 2>

or
    try:
        <block 1>
    except ...:
        <block 2>

if 2to3 would translate <block 1> to <block 2> or vise versa, sans
whitespace/comment differences, then it does not do so.  Instead it
assumes the blocks are for running under Python 2 and 3 respectively.
