Here's a series that does that, with a few other cleanups on top. The
diffstat actually ends up a few lines longer, but that is mostly because
of comments and function declarations. More importantly, though, the
call-sites are much easier to read.
Having written this series, though, I can't help but wonder if the world
would be a better place if config_fn_t looked more like:
typedef int (*config_fn_t)(const char *full_var,
const char *section,
const char *subsection,
const char *key,
const char *value,
void *data);
It's just as easy for the config parser to do this ahead of time, and by
handing off real C-strings (instead of ending up with a ptr/len pair for
the subsection), it makes the lives of the callbacks much easier (e.g.,
the final patch below contorts a bit to use string_list with the
subsection).
I can look into that, but here is the less invasive cleanup:
[1/6]: config: add helper function for parsing key names
[2/6]: archive-tar: use match_config_key when parsing config
[3/6]: convert some config callbacks to match_config_key
[4/6]: userdiff: drop parse_driver function
[5/6]: submodule: use match_config_key when parsing config
[6/6]: submodule: simplify memory handling in config parsing
