This question led to a new package:
impnattypo
The French government publications office (Imprimerie Nationale) publishes a list of recommendations for French typography. I'm wondering how to implement some of these in LaTeX. I might actually come up with more later as I continue reading this booklet.
End of chapters/parts
In addition to the recommendations of removing footers on the last page of chapters/parts, it is recommended that these pages do not have less than 6 lines. I am guessing (it is not written) that if there are less than 6 lines, it is recommended to increase that number by forcing a page break in (one of) the previous page.
Hyphenation rules
- No odd page should finish with an hyphenated word;
- No more than 3 lines with hyphenated words should follow one another.
