I have an azure git repository which contains special characters that are correctly escaped in the URL (e.g. as %20). Example: https://sombody@dev.azure.com/sombody/TEST%20WHAT%C3%A4ver/_git/WebApi In the Remote-Edit-Dialog the URL is shown as invalid. Maybe the regex should be expanded with "%" to allow this kind of URLs. (Beside this dialog, It seems to work file) http[s]?://([\w\-%]+@)?[\w\.\-%]+(\:[0-9]+)?/[\w\-/~%]+/[\w\-%\.]+(\.git)?$
