I have a rather large text only document using justified text (yes, a book 
) that I have had to change the font and margins in several times. Each time I do this line breaks change all over the place, and I have to manually read through the entire document to check if there are any too long words in the beginning of a line (causing the line before to have the words stretched too far apart). I cannot use auto hyphenation in my language, the quality is too low. All hyphenation has to be done manually.
My question is: Is there any way (maybe using a macro?) to find all places where the word spacing is stretched over a certain limit (like 20 points for example) ?
Illustration: I want to detect the line with a red marker underneath in the example below.
