* gdb.base/help.exp ("help delete display"): Fix test to match
gdb's output.
* gdb.base/long_long.c (known_types): Initialize values to zero.
* gdb.base/long_long.exp: Step one more line
so 'dec' is initialized in "get to known place". GDB doesn't
prepend unnecessary zeros to the front of numbers. Explicitly
ask for hex formatting. Use unique test case names.
