[bug-mailutils] Problems with new mailutils mh programs

[d.henman]

The communications portions of the gnu-mh is working for me, but there is some 
inter-operability problem between the newer mailutilities gnu-mh and emacs's 
MH-E.

#1 On MH-E start-up I'm always getting a "scan: bad message list `unseen'" 
message.

 ~/mh_profile contains:
   
Unseen-Sequence: unseen

$mail/inbox/.mh_sequence  contains:
subject: 24 57 62
cur:  29

#I don't know what the file .mu-prop is for but it contains:
uid-validity: 1364610333
size: 301426

Note: that scan for unseen messages give the following error.

$ scan unseen
scan: bad message list `unseen'

This behavior is also seen on other platforms,  so it it not platform specific. 
 It seems to be related with sequences.

Please take a look at the behavior.  I have noticed another problem when 
working with sequences, for example in deleting a sequence with the same 
subject in emacs MH-E.

The gnu-mh 'burst' program also behaved (or caused MH-E) to behave strangely.
I'm looking into it, so I can report it better.

Thanks
