While seeing how to decode a 'roll your own' format string is an interesting
exercise, we definitely are reinventing the wheel here. All this code really
does is translate your format specifier scheme into Python's own. As Magnus
pointed out, you really should take a look at
http://www.python.org/doc/current/lib/typesseq-strings.html . It lists all
of the string formatting specifiers that Python uses.

scientific notation:

>>> '%20.5e' % .045678957
'        4.56790e-002'

octal:

>>> '%10o' % 4096
'     10000'
