Patch for MH-E code

[jdh]

Here is patch supplied by Sergey of Gnu Mailutils,
which is needed to keep MH-E code compatible with Gnu Mailutils MH, Gnu-MH.
Below the mh-comp.el-unpatched.el is what you now have as the curren

Please see that it gets incorporated into temacs

A short explanation would be in place, perhaps. When working with
directory-like mailbox folders (i.e. MH and Maildir), GNU Mailutils
stores some meta-information about the folder and its content in
the file .mu-prop, placed in the folder itself. So, in case of the
code snippet in question, simply removing .mh_sequences is not enough,
because .mu-prop still remains and causes delete-directory to fail.
Recursive deletion fixes the problem.

Regards,
Sergey
