  16 # Be careful when updating this list:
  17 #
  18 # (1) The build tree may have build artifact from different branch, or
  19 #     the user's $PATH may have a random executable that may begin
  20 #     with "git-check" that are not part of the subcommands this build
  21 #     will ship, e.g.  "check-ignore".  The tests for completion for
  22 #     subcommand names tests how "check" is expanded; we limit the
  23 #     possible candidates to "checkout" and "check-attr" to make sure
  24 #     "check-attr", which is known by the filter function as a
  25 #     subcommand to be thrown out, while excluding other random files
  26 #     that happen to begin with "check" to avoid letting them get in
  27 #     the way.
  28 #
  29 # (2) A test makes sure that common subcommands are included in the
  30 #     completion for "git <TAB>", and a plumbing is excluded.  "add",
  31 #     "filter-branch" and "ls-files" are listed for this.
