Code smell: Use ||= for conditional initialization

Replaced 55 occurances of

    ([$@]?\w+) += +(.*) +(if +\1.nil\?|if +! *\1|unless +\1|unless +defined\?\(\1\))$

with

    \1 ||= \2

3 Examples:

    The code:
        @sync
    becomes:
        @sync
    The code:

    becomes:

    The code:
        if @yydebug
    becomes:
        if @yydebug
