When the config parser sees an "implicit" bool like:
[core]
someVariable
it passes NULL to the config callback. Any callback code which expects a
string must check for NULL. This usually happens via helpers like
git_config_string(), etc, but some custom code forgets to do so and will
segfault.
These are all fairly vanilla cases where the solution is just the usual
pattern of:
if (!value)
return config_error_nonbool(var);
though note that in a few cases we have to split initializers like:
int some_var = initializer();
into:
int some_var;
if (!value)
return config_error_nonbool(var);
some_var = initializer();
There are still some broken instances after this patch, which I'll
address on their own in individual patches after this one.
