convert/darcs: support changelogs with bytes 0x7F-0xFF (
issue2411)
This is a followup to
4481f8a93c7a, which only fixed the conversion of
patches with UTF-8 metadata.
This patch allows a changelog to have any bytes with values
0x7F-0xFF. It parses the XML changelog as Latin-1 and uses
converter_source.recode() to decode the data as UTF-8/Latin-1.
Caveats:
- Since the convert extension doesn't provide any way to specify the
source encoding, users are still limited to UTF-8 and Latin-1.
- etree will still complain if the changelog has bytes with values
0x00-0x19. XML only allows printable characters.
revset: add id() and rev() to allow explicitly referring to changes by hash or rev
