Okay. That would also support user paths.
There is a problem, though: `git_config_pathname()` accepts a `const char **`
parameter to set the path, yet I need to `free()` that pointer afterwards
because it has been obtained through `expand_user_path()` which detaches that
buffer from a `strbuf`.
In regular use cases, that does not matter much because the path obtained via
`git_config_pathname()` is typically stored in a global variable, but in my
case, I append it to a global variable.
Of course I could cast the value to a `char *` and `free()` it, but that would
assume too much about the implementation detail of `git_config_pathname()` for
my taste.
The easiest cop out would be to recapitulate the code in
`git_config_pathname()`, but I think the correct solution would be to change
the signature of `git_config_pathname()` to accept a `char **` instead. Do you
agree? However, the diff looks really ugly:
