Summary

0000248: sed y// doesn't behave as defined by standard sed

Description

The y// text transformation command in busybox sed does not function properly.

here's an example (rot13 of "Hello World!"):
echo 'Hello World!' | sed -e 'y/abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ/nopqrstuvwxyzabcdefghijklmNOPQRSTUVWXYZABCDEFGHIJKLM/'

standard gnu sed output: Uryyb Jbeyq!
busybox sed output: Hellb Jbeld!

The output appears as though the replacement happened for each replacement set over the whole string each time, iteratively. So, all a's in the string are replaced by n, b's replaced by o, [...] n's replaced by a (even ones that were originally a, replaced by n when that first happened).

This should not happen, once a replacement happens, the character should be taken out of the list.
