/* Someday we should allow demangling for things other than just
explicit strings. For example, we might want to be able to specify
the address of a string in either GDB's process space or the
debuggee's process space, and have gdb fetch and demangle that
string. If we have a char* pointer "ptr" that points to a string,
we might want to be able to given just the name and have GDB
demangle and print what it points to, etc. (FIXME) */
