Also MacOSX ReadMe files. Note that a few lib/doc files are
also "updated" because trailing spaces are removed, but their file
formats are the same because they were recently updated at 83672113.
I did "git checkout LFUNs.lyx" because this file is generated

- also disable PDF-reply since this never works correctly and it could even destroy the whole PDF and exceeds the TeX capacity
- update the french version accordingly
