# 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.
