You would have seen the same results had you specified the `-e' option
to echo. The behavior is consistent, and will remain so.

I don't believe it's "too late", considering that you had to compile bash
with a non-default set of configuration options to encounter the problem.
However, I like consistency, and I believe that it's important to have
-e and the xpg_echo option produce identical output.
I don't favor being deliberately incompatible, though, unless there's a
compelling reason. This doesn't seem to measure up to that standard.
The remaining consideration is whether or not there's a significant
body of scripts out there that rely on the current behavior. If there
isn't, I would strongly consider the change to require a leading `0'
in octal constants. I don't think that \x introducing hex constants
is as big a problem (it may not be a problem at all).
