This commit probably needs a bit of intro text.

This sort of approach isn't very i18n-friendly.  I think we've been
trying to avoid introducing new code like this, in hopes that maybe
somebody will provide gdb translations some day.

One idea might be to separate the main text from the parenthetical text,
so like:

  printf_filtered (_("Source files for which symbols have been read in"));
  if (blah)
    printf_filtered (_("(dirname matching regular expression \"%s\")"), dirname);
  ...
  printf_filtered (_(":\n"));

The "if"s could be factored into a helper function.

Otherwise this patch seems good to me.  Thanks for doing this.
