mh-coalesce-msg-list

mh-coalesce-msg-list is an autoloaded Lisp function in `mh-utils.el'.

(mh-coalesce-msg-list MESSAGES)

This is the inverse of `mh-read-msg-list', which expands ranges.
Message lists passed to MH programs should be processed by this
function to avoid exceeding system command line argument limits.
