Created attachment 201850 [details] forum-fr-45727.doc: 91 pages of justified text I ran across this nice, long, justified document that seems to be fairly simple - just using the Times New Roman font. However, our justification (in 25.8) no longer matches the output I got from MS Word. During my bibisect, I focused on the top of page 31, the paragraph: A.D. : Je veux dire, je savais que vous veniez et puis bon, y'a des choses, on a eu d'autres stagiaires, donc c'est des choses dont on l'habitude de... Voilà, mais on vous donnera des documents si besoin. In MS Word it fits on two lines, but in master it takes up three lines.

Or is this yet another new edge case that smart justify needs to deal with? Found by Collabora's mso-test.
