!*$
 * M[opener] -- Open a number of files from the current buffer
 *
 * This is usually the unnamed buffer as initialized from the command line.
 * It supports both the +line[,column] and filename:line[:column] syntaxes.
 * Since this may make it hard to open files with certain file names, all
 * filenames after "--" are interpreted verbatim.
