Fixed output of *ROMModules so everything lines up properly.

Detail:
  The code for *ROMModules uses OS_PrettyPrint, which seems unconcerned
    by such trivial things as leading spaces, which accounts for the
    misaligned output.  The code now starts by using ASCII 31 (hard
    space for OS_PrettyPrint's purposes) as the leading indent character
    to avoid confusion.
Admin:
  Tested on desktop build in both command-line and TaskWindows.
