Attached is a patch for Text.PrettyPrint.HughesPJ that adds a 'hex'
function to print hexidecimal numbers.
The only point that I exepect to be contended is it varies slightly from
the surrounding functions in that it allows one to control the number of
characters printed (see below).
> hex 5 31
0001f
> hex 2 8
08
> hex 3 7495
d47
While we can argue about the consistancy issues, I almost always want to
control the number of digits when I'm dealing with hex. Hence I feel this
is a reasonable special case.
