 * M[opener] -- Open files, specified on 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.
 * It does not change the current buffer.
