Addition: A main reason for the disruption when navigating fast seems to be that guess-language rechecks ALL paragraphs navigated over. This can be 10s of paragraphs, all in different languages, leading ultimately to a large blocking time. The patch avoids this by only checking the paragraph the point is in (and ignoring paragraphs "moved over"). The "run-with-idle-delay" that's currently used in guess-language is probably not needed anymore in case this patch is accepted, but it also doesn't hurt. |

guess-language rechecks a paragraph's language whenever an incorrect word is found and, if necessary, changes the language and reruns ispell. When quickly navigating through a buffer that uses many languages (such as large org files), these somewhat time-consuming process disrupts navigation.
This patch adds an option to run guess-language after a short idle delay, which fixes this problem. It also enables this option by default, using a short but sufficient idle delay.
