`maint demangle' only works for me when I explicitly run gdb on a C++
program.  When I do specify a C++ program, it appears to work
correctly.

Otherwise, I see that maintenance_demangle() calls
language_demangle().  When I try running gdb without an explicit C++
program, either current_language is NULL or
current_language->la_demangle is NULL, so language_demangle returns
NULL.
