-1 on "c" It's too visually close to "0" in some fonts.

+1 on "t"

"t" does not appear in 'binary' or 'hexadecimal'
"x" does not appear in 'binary' or 'octal'
"b" does not appear in 'octal' or 'hexadecimal'

And finally "c" means "character" in %s or PEP3101, and "t" is not yet
defined as a type specifier.

So just to couch it all in terms of a proposal:

- In 2.6 and 3.0, we add 0t1234 as a valid octal number
- In 2.6, we issue a deprecation warning for a leading literal 0 which
is followed immediately by another digit.
- In 3.0, that becomes an exception
- If people really are still using octal that much, we should also
consider adding it in to PEP3101.
