Basically I get :
Note that :
- first the new lint for xxx is not separated from previous block so it makes prety hard to detect it (i didn't) but
- the FilenameLinter did print that it accept only letter, number, period but Cahier_des_charges....docx wasn't accepted since the C : so a lowercase letter in the description would be more appropriate.
- contrary to other linters that clearly highlight the part that falls, filename did not !
