fetch progress information is available but dropped

jorhett

Modern versions of git will return progress information. In debugging what goes on here, I found that all of the information was being dropped by _parse_line. For others who run into this, I was able to return branch update information to the user by adding the following:

class SeeFetchProgress(git.remote.RemoteProgress):
    # the implementation of RemoteProgress currently doesn't match fetch lines, so catch them when dropped.
    def line_dropped(self, line: str):
        if re.match('remote: ', line):
            return
        print(line)
