Enable xfce4-minicmd-plugin to launch web- and ftp-adresses

Hi

I'm very new at this, but I'v been using gnu/linux now and I know basic 
programming. I love Xfce4 but I found it frustrating that you couldn't 
launch a browser or ftp-client by entering that kind of address in the 
mini-command-line so I wrote a tiny hack :P  It's not very pretty code and 
I/you should make it configurable so that the user can select which browser 
to use for ftp sftp and http - maybe something for the settings manager?

Anyhow since I want to help but don't know where to send my code I post it 
here (it's not very long). Please send suggestions and tell where I should 
send my code

///// in command.c    I add these two functions

gboolean cmd_is_httpaddress(const char * cmd)
{
  return(!strncmp(cmd, "http://", 7) || !strncmp(cmd, "www.", 4));
}

gboolean cmd_is_ftpaddress(const char * cmd)
{
  return(!strncmp(cmd, "ftp://", 6) || !strncmp(cmd, "sftp://", 7) );
}

/// end code


Then I modify do_run  into this

static gboolean do_run(const char *cmd, gboolean in_terminal)
{
    gchar *execute, *path;
    gboolean success;

    g_return_val_if_fail(cmd != NULL, FALSE);


    /* check if the user has entered a http or www command */
    if (cmd_is_httpaddress(cmd))
    {
      execute = g_strconcat("firefox ", cmd, NULL);
      success = exec_command(execute);
      g_free(execute);

      return success;
    }

    /* check if the user has entered a sftp or ftp command */
    if (cmd_is_ftpaddress(cmd))
    {
      execute = g_strconcat("nautilus ", cmd, NULL);
      success = exec_command(execute);
      g_free(execute);

      return success;
    }

// and the function continues

What do you think? My solution is not very pretty but it sure works (not 
very safe though), and it can be modifies into becoming a lot more 
configurable, but I just needed this code for myself so I wrote it :P  Maybe 
you like it too?
