  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.
