hg ishow fails in clone of Artemis-repo

[Mirko Friedenhagen <mirko@friedenhagen.de>]

Hello Dmitriy,

first of all let me thank you for this extension, I have the feeling  
that it might be really useful.

I have one issue with the clone, "hg ilist" will abort, "hg ishow"  
does not have any problems:

[mirko@borg Artemis]$ hg log -l1

Add ability to attach files in iadd command. Perhaps use -a flag for
it (allowing multiple attachments). Store as a multipart message. List
all parts of messages in ishow.
