If I am not mistaken then Git exits with 0 (success) and an error message
if the filter command is empty and the filter is not required. If the filter
command is empty and the filter is required then Git will exit with 1 (error).
How about this?
If the clean/smudge command of a Git filter driver (filter.<driver>.smudge and
filter.<driver>.clean) is set to an empty string ("") and the filter driver is
not required (filter.<driver>.required=false) then Git will run successfully.
However, Git will print an error for every file that is affected by the filter.
Teach Git to consider an empty clean/smudge filter as legitimately disabled
and do not print an error message if the filter is not required.
Thanks,
Lars
