mail: add methods to handle non-ascii chars
- headencode, addressencode: encode headers
- mimeencode: encode message parts not containing patches
- new email config "charsets"
Users may configure email.charsets as a list of charsets they
consider appropriate for the recipients of their outgoing mails.
Conversion is tried in this order:
1. us-ascii
(ascii, us-ascii are removed from email.charsets if present)
2. email.charsets (if present) in order given
3. util._fallbackencoding, util._encoding, utf-8
if not already in email.charsets
mq: Allow qrefresh --silent to take parameters
'hg qrefresh --short file.txt' now adds changes made to file.txt to current
patch.
This builds on a patch for implementing --amend by Kirill Smelkov as discussed
in
issue933.
FIXME: Why do mq refresh have two matchers if we only need one?
Add parseindex2.py test case
Make sure that the new implementation in C return that same values as the
original Python implementation.
