Not a problem this patch introduces, but it looed funny to see the
second line abut to the left edge of the page there.
In any case, the updated semantics look quite sensible.

The flow looks nice, but the pre-context of this hunk starts like
this:
if (!value)
return config_error_nonbool(var);
if (!strcmp(value, "never")) {
cfg->autocorrect = AUTOCORRECT_NEVER;
} else if (!strcmp(value, "immediate")) {
cfg->autocorrect = AUTOCORRECT_IMMEDIATELY;
} else if (!strcmp(value, "prompt")) {
IOW, the new code added at the end of the if/else if/ cascade is way
too late.
"[help] autocorrect"
that specifies "true" has already been rejected as an error, with a
now-stale error message saying that the variable is not a Boolean.
We may probably want to use git_parse_maybe_bool_text() upfront,
like
static int parse_autocorrect(const char *value)
{
switch (git_parse_maybe_bool_text(value)) {
case 1:
return AUTOCORRECT_IMMEDIATELY;
case 0:
return AUTOCORRECT_NEVER;
default: /* other random text */
break;
}
if (!strcmp(value, "prompt"))
return AUTOCORRECT_PROMPT;
...
if (!strcmp(value, "prompt"))
return AUTOCORRECT_PROMPT;
return 0;
}
and then in git_unknown_cmd_config(), do something like
if (!strcmp(var, "help.autocorrect")) {
int v = parse_autocorrect(value);
if (!v) {
v = git_config_int(var, value, ctx->kvi);
if (v < 0)
v = AUTOCORRECT_IMMEDIATELY;
}
cfg->autocorrect = v;
}
perhaps?
