   3# A remote repository can be specified on the command line
   4# in one of the following formats:
   5#
   6#       <repo>
   7#       <repo> <head>
   8#       <repo> tag <tag>
   9#
  10# where <repo> could be one of:
  11#
  12#       a URL (including absolute or local pathname)
  13#       a short-hand
  14#       a short-hand followed by a trailing path
  15#
  16# A short-hand <name> has a corresponding file $GIT_DIR/branches/<name>,
  17# whose contents is a URL, possibly followed by a URL fragment #<head>
  18# to name the default branch on the remote side to fetch from.
