input.c: simplify command definitions

Using type = -1 for terminating the command argument list was an
unnecessary complication. Change it to 0 to make use of default
initialization. Remove the explicit termination from the command
definitions. Now the argument list is automatically terminated by C
default initialization rules.

Also remove other redundant {0} initializers.

When an argument's default value is actually initialized to something other
than 0, make the field being initialized explicit (e.g. {1} becomes
{.i = 1}).

Try to make use of whitespace more consistent.
