mail: add parseaddrlist() function for parsing many addresses at once
Adds a new function addrlistencode() to mercurial.mail, like addressencode(),
but accepts a list of addresses as input, and returns a list of formatted
addresses. This will be used by patchbomb.
The difference is that each element in the input list can contain multiple
addresses (comma separated or otherwise), and are split using Python's
email.Utils.getaddresses().
Mercurial's documentation is kept in reStructuredText format, which is
a simple plain text format that's easy to read and edit:
http://docutils.sourceforge.net/rst.html
It's also convertible to a variety of other formats including standard
UNIX man page format and HTML. You'll need to install Docutils:
http://docutils.sourceforge.net/
Use the Makefile in this directory to generate the man and HTML pages.
