Only a single slash (/) is now necessary to repeat a search as per Theo's
request. So the command: /pattern/;/ finds the second line containing "pattern" after the current line. Caveat: The commands `st' and `sr' are now both legal and have very different meanings. This is because ed(1) extends POSIX to include the old Berkeley syntax s[rgp]*. (So should two slashes still be required in the case of the substitute command, as SunOS ed does?)
