export: show 'Date' header in a format that also is readable for humans
'export' is the official export format and used by patchbomb, but it would only
show date as a timestamp that most humans might find it hard to relate to. It
would be very convenient when reviewing a patch to be able to see what
timestamp the patch will end up with.
Mercurial has always used util.parsedate for parsing these headers. It can
handle 'all' date formats, so we could just as well use a readable one.
'export' will now use the format used by 'log' - which is the format described
as 'Unix date format' in the templating help. We assume that all parsers of '#
HG changeset patch'es can handle that.

Rebase - try to rebase on an applied mq patch:
$ hg rebase -s 1 -d 3
abort: cannot rebase onto an applied mq patch

Rebase - same thing, but mq patch is default dest:

$ hg rebase
abort: cannot rebase onto an applied mq patch

Rebase - generate a conflict:

Fix the 1st conflict:
$ echo mq1r1 > f
$ hg resolve -m f
$ hg rebase -c
