+# 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.
