Underscores after short hex/octal chars in 5.6.0

 Underscores after short hex/octal chars in 5.6.0

I've run into some unusual behavior in 5.6.0 when underscores follow short
octal and hex character specifications. ("Short" meaning that they have
just one or two characters for octal or just one for hex.) But maybe it's
some new Unicode thing I'm unaware of?

    $ perl -lwe '$_ = "\0___"; print length;'

The string in this case is an ASCII NUL followed by an underscore.

It's as if the parser is insisting upon getting three octal or two hex
digits when underscores follow the character specifier. I'm pretty sure
this is a bug; if it's a feature, I didn't find it in the docs.

Opinions or patches?
