When using `shellcheck --format=json1`, csgrep output is missing position information

[jamacku]

How to reproduce

shellcheck --format=gcc script.sh | csgrep
Error: SHELLCHECK_WARNING:
innocent-script.sh:6:1: warning[SC2034]: UNUSED_VAR appears unused. Verify use (or export if used externally).

shellcheck --format=json1 script.sh | csgrep
Error: SHELLCHECK_WARNING:
innocent-script.sh:6: warning[SC2034]: UNUSED_VAR appears unused. Verify use (or export if used externally).

Please notice the missing 1 in the second output:

- innocent-script.sh:6:1: warning[SC2034]: UNUSED_VAR appears unused. Verify use (or export if used externally).
+ innocent-script.sh:6: warning[SC2034]: UNUSED_VAR appears unused. Verify use (or export if used externally).
