Thanks, you must have run the long checks. I know why this is failing:
it's due to a difference between the results with the Perl XS
paragraph formatting module. My previous attempt to fix this test
failed, so now I've turned off XS for all the tests under tp/tests.

(The difference is how the screen width of combining characters is
counted, leading to a difference like this:

address@hidden -a̲ address@hidden ạ address@hidden -ạ address@hidden
-ǎ address@hidden -ǎ ‘@,{c}’ ç ‘@,{--c}’ -ç address@hidden footnote}’ (1)
address@hidden -a̲ address@hidden ạ address@hidden -ạ address@hidden ǎ
address@hidden -ǎ ‘@,{c}’ ç ‘@,{--c}’ -ç address@hidden footnote}’ (1)

In the pure Perl code, the width of one of the accented characters is
being treated as 2 instead of 1, making the first line shorter.)
