Bad news: when I tried to type an isearch string on a large file
(about 1MB) after typing the first character 'e' lazy-highlighting
became unresponsive busy highlighting all 50000 matches in that file.

Do you think we should start lazy-highlighting for the full buffer
only when the length of the search string is more than 1 character?
