convert/darcs: handle non-ASCII metadata in darcs changelog (issue2354)

Given a commit author or message with non-ASCII characters in a darcs
repo, convert would raise a UnicodeEncodeError when adding changesets
to the hg changelog.

This happened because etree returns back unicode objects for any text
it can't encode into ASCII. convert was passing these objects to
changelog.add(), which would then attempt encoding.fromlocal() on
them.

This patch ensures converter_source.recode() is called on each piece
of commit data returned by etree.

(Also note that darcs is currently encoding agnostic and will print
out whatever is in a patch's metadata byte-for-byte, even in the XML
changelog.)

use 'echo' to diff repository (or selected files)

    Show differences between revisions for the specified files, using the
    'echo' program.

    When two revision arguments are given, then changes are shown between
    those revisions. If only one revision is specified then that revision is
    compared to the working directory, and, when no revisions are specified,
    the working directory files are compared to its parent.

options:

 -o --option OPT [+]       pass option to comparison program
 -r --rev REV [+]          revision
 -c --change REV           change made by revision
 -I --include PATTERN [+]  include names matching the given patterns
 -X --exclude PATTERN [+]  exclude names matching the given patterns

[+] marked option can be specified multiple times

use "hg -v help falabala" to show global options
