I've just come across an omission in re.sub which I hadn't noticed
before.
In re.sub the replacement string can contain escape sequences, for
example:
>>> repr(re.sub(r"x", r"\n", "axb"))
"'a\\nb'"
However:
>>> repr(re.sub(r"x", r"\x0A", "axb"))
"'ax0Ab'"
Yes, it doesn't recognise "\xNN".

As long as there's a way to place a single backslash in the output
this seems fine to me, though I'm not sure it's important. Of course
it will likely break some test... the test will then have to be fixed.
I can't remember why we did this -- is there a full list of all the
escapes that re.sub() i

Howeve
I guess the current rule is that any escapes referring to characters
by a numeric value are not supported; this probably made some kind of
sense because \1 etc. are backreferences. But since we're discouraging
octal escapes anyway I think it's fine to improve over this.

What do you think is the reason? It's not at all obvious to me.

If you run "build" repeatedly (e.g. in a development cycle), then

Are you talking about general porting, or about Twisted?
It is a common misconception that "drop everything prior to 2

Yeah ok, I marked the function as private: renamed to _PyUnicode_Copy() and I
undocumented it.

Martin,
You seem heavily invested in minidom.
In the near future I will need to parse and rewrite parts of an xml file
created by a third-party program (PrintShopMail, for the curious).
It contains both binary and textual data.
Would you recommend minidom for this purpose? What other purpose
