I was compiling with DEVELOPER=1 but as it turns out:

    CFLAGS="-O0" DEVELOPER=1

Wasn't doing what I thought, i.e. we just take 'CFLAGS' from the
command-line and don't add any of the DEVELOPER #leftoverbits to
it. Will fix this and other issues raised.

Will fix this and other issues raised. FWIW clang gives a much better
error about the actual issue:

    remote.c:1042:46: error: cannot mix positional and non-positional arguments in format string [-Werror,-Wformat]
                    "- Checking if the <src> being pushed ('%2$s')\n"

I.e. this on top fixes it:

    -               "- Looking for a ref that matches '%s' on the remote side.\n"
    -               "- Checking if the <src> being pushed ('%s')\n"
    +               "- Looking for a ref that matches '%1$s' on the remote side.\n"
    +               "- Checking if the <src> being pushed ('%2$s')\n"

Maybe  this whole thing isn't worth it and I should just do:

    @@ -1042 +1042 @@ static void show_push_unqualified_ref_name_error(const char *dst_value,
    -               "- Checking if the <src> being pushed ('%2$s')\n"
    +               "- Checking if the <src> being pushed ('%s')\n"
    @@ -1047 +1047 @@ static void show_push_unqualified_ref_name_error(const char *dst_value,
    -             dst_value, matched_src_name);
    +             dst_value, matched_src_name, matched_src_name);

But I'm leaning on the side of keeping it for the self-documentation
aspect of "this is a repeated parameter". Your objections to this whole
thing being a stupid idea non-withstanding.
