Hmm... if someday someone wants git-status to support a status.verbose
config variable, with Pranit's current implementation, it's a pretty
simple change: Just add to git_status_config():
if (!strcmp(k, "status.verbose")) {
int is_bool;
config_verbose = git_config_bool_or_int(k, v, &is_bool);
return 0;
}
and in cmd_status() change:
if (verbose == -1)
verbose = 0;
to:
if (verbose == -1)
verbose = (config_verbose < 0) ? 0 : config_verbose;
It wouldn't be too hard with your proposal either: Either add a
'config_status_verbose' variable or rename 'config_commit_verbose'
back to 'config_verbose', initialize the global 'verbose' to -1, drop
the explicit 'verbose = -1' from cmd_commit(), and make the same
changes shown for Pranit's version. The diff would be a bit noisier.
I do like that your proposal makes it more difficult for
commit.verbose to break git-status, but otherwise don't feel that it
is significantly better. So, I dunno...
