When we see the core.commentchar config option, we extract
the string with git_config_string, which does two things:
1. It complains via config_error_nonbool if there is no
string value.
2. It makes a copy of the string.
Since we immediately parse the string into its
single-character value, we only care about (1). And in fact
(2) is a detriment, as it means we leak the copy. Instead,
let's just check the pointer value ourselves, and parse
directly from the const string we already have.
