There are some "specific interpretations" that _may_ be
interpreted according to the C rules, e. g. prefix 0x-
for hexadecimal or 08- for octal notation. For example,
083 != 83, just as 0x83 != 83. As it has been mentioned,
spaces also have a significant meaning in crontabs, so
they cannot be used everywhere to align data columns.
