16 # Be careful when updating this list:
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.
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.
