* tc/http-urls-ends-with-slash:
  http-fetch: rework url handling
  http-push: add trailing slash at arg-parse time, instead of later on
  http-push: check path length before using it
  http-push: Normalise directory names when pushing to some WebDAV servers
  http-backend: use end_url_with_slash()
  url: add str wrapper for end_url_with_slash()
  shift end_url_with_slash() from http.[ch] to url.[ch]
  t5550-http-fetch: add test for http-fetch
  t5550-http-fetch: add missing '&&'
