   In our Sun C compiler, printf("%#07x", 27); prints "0x000001b" (9 characters)
while printf("%#7x", 27); prints "   0x1b" (7 characters). Is this a) common,
b) "correct", c) discussed in the ANSI standard?  My feeling is that the two 
format strings should always generate 7 characters (unless more are necessary 
to represent the number), and losing this battle I would at least hope they 
would both generate 9 characters (either the "0x" is part of the field width 
or it isn't).
