Excuse me, but what alternate universe did you get your C Reference manual
from?  Both of the two above statements have the *exact same effect* in C;
they cause "argv" to point to the pointer that follows the one it pointed to
before the statement.

The C Reference Manual:

	7.2 Unary operators

	...The expression ++x is equivalent to x += 1.
