convert from hexidecimal or octal to decimal

Bash can accept '0x' and '0' notation for hexidecimal and octal numbers, so you just have to output the values.

What others think

obase can be in the range 2-16 and does what you'd expect. I tried it with obase=17 and it did a safe but boring thing: gave me space separated decimal numbers for each digit.
