    '\n' +
    '&gt; Remove the ENABLE_QUOTA compile-time flag.\n' +
    '&gt; \n' +
    '&gt; This patch drops the ~20 occurances of \'#IFDEF ENABLE(QUOTA)\' from the\n' +
    '&gt; codebase. It shouldn\'t effect any web-visible behavior, as the interesting\n' +
    '&gt; bits are still hidden away behind the runtime flag, whose behavior\n' +
    '&gt; is untouched by this patch.\n' +
