Hi Juri,

Thanks for working on this.

I don't know this code too well, but perhaps SEARCH_STRING here should 
be anchored with something like "\\=" at the beginning?

Otherwise the search can succeed here even if the next match is not 
here. Not sure how important that is, though.

Please note that we'll likely have to keep this code here for a number 
of Emacs releases. So the patch should be tested with both versions: 
with this code present and with it removed, to ensure present and future 
compatibility.
