I find that there are some  sub-commands can't be completed by TAB key:

$ git <TAB>
add               cherry-pick       fetch             latexdiff
[...]
As you can see, there are some sub-commands which are not listed in
the above list, for example, the following ones:

$ git ls-remote
$ git ls-files

Any hints for this problem?

Tab completion is only available for user-facing sub-commands
("porcelain"), but not for sub-commands intended for scripting
("plumbing"). The intent is to make tab completion more efficient during
day-to-day work on the command line. For example,

   $ git l<TAB>

arrives at

   $ git log <cursor here>

instead of

   log     ls-files     ls-remote     ls-tree
   $ git l<cursor here>
