Bug in $if version parsing

[Tom Tromey]

I change the GDB test suite to use this inputrc:

    $if version >= 8.0
    set enable-bracketed-paste off
    $endif

However, to my surprise, this did not work.  I believe this is a bug in
bind.c:parser_if.

This function computes 'op' as 'OP_GE' (ok so far), but then does:

        case OP_GE:
          _rl_parsing_conditionalized_out = rlversion >= versionarg;
          break;

This sets _rl_parsing_conditionalized_out to 1, but it should be 0.
I think all of these results should be inverted.  See the appended patch
for what I mean.
