(* or ?) chars are present.  Doing so prevents re-writing of the path
parameter, so behaviour is different between the two.

This would break something like:
int munlink(char *glob)
{
        char    this[MAX_PATH+1];

        strcpy(this,glob);
        while(fexistcase(this)) {
                unlink(this);
                strcpy(this,glob);
        }
}

Does Synchronet rely on the old behaviour anywhere?
