Based on this short description I would expect that this "command
stuff" is calculated somewhere, and a helper function is changed to
use the already calculated value ...

... but the bulk of this change is in the top-level _git() function,
as it renames a variable there to match the variable name in the
helper function. Perhaps it should be the other way around.
However, this change "promotes" the command (or cmd) variable from
being just a variable in _git() to a variable that is used in other
completion functions, too. Why not go one more step further, and
denote this by adding a __git prefix (i.e. renaming the variable to
__git_command)?
Best,
Gábor
