When you read the pages for the additional days, you see that
they are printed with a day number and a day-of-week name.
Thank you, that is a primary source! Of course we know little about the
context: it may have been written that way for sake of a uniform presentation.
However, being no scholar of the republican calendar I will leave that
judgement to you.
About lower case vs upper case: The French convention for
Revolutionary names may be different from the French convention
for Gregorian names. Most often, the revolutionary month names
and day names are printed with an initial capital letter.
Yet, there are exceptions. See the front page (link above)
which mentions the "9 floréal an 7" with a lower case "f".
Yes, it is a fair assumption that the usage conventions were less rigid in
those days, and it can have been a matter of whether the words occurred in a
title or in running text. The (French) Wikipédia article uses predominantly
lower case but it obviously follows modern conventions. Again, your call.
Feel free to base your changes on my previously posted diff, but give it a good
read-through so that the changes are indeed exactly those that you intended.
Also, we'd be happy if you wrote some tests;
test/lisp/calendar/cal-french-tests.el would be a suitable place.
