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