This is similar in spirit to the helper flags in git subcommands, e.g.
try `git branch --git-completion-helper`. It provides a list of long
flags that the subcommands support, without repeating it manually in the
completion script. Note that this special flag is not returned in help,
so there is no noise.
To see the result, source the script, then `git cl upload --<TAB>`.

The commands come from the output of git cl -h, which then goes through
an sed filter, matching on the ANSI escape sequence for green and reset.
This ends up having extra spaces, since the output aligns the
subcommands based on the longest subcommand. For shorter commands like
archive, it becomes "archive ". So, tweak the sed regex to only
capture the part without the whitespaces.
