[Dillo-dev] [patch] phrase search - take 2

Hi, here comes my second attempt on phrase search. As already described, I changed CharIterator back to not return \0s. Instead blanks are inserted when the space flag is set. This way CharIterator always returns a smooth stream of chars whether for normal html- or pre-text. Then there was a bug in DeepIterator::prev() that took me some time to find. I also adjusted charsEqual() to treat all space-chars equally. Finally I had to add a check in CharIterator::highlight() to avoid a crash when searching for the last word in pre-text with a blank appended. Cheers, Johannes
