* mh-comp.el (mh-display-completion-list-compat): New macro which
calls `display-completion-list' correctly in older environments.
Versions of Emacs prior to version 22 lacked a COMMON-SUBSTRING
argument.
(mh-complete-word): Use it.
* mh-init.el (mh-image-load-path): Use locate-library to find
MH-E. This simplified the code a lot. Flattened out nested
statements even more.
