* Only a single slash (/) is now necessary to repeat a search as per Theo'salm1993-08-271-5/+2
| | | | | | | | | | | 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?)
* 1003.2 requires that lexical comparisons be done in locale specific manner,jtc1993-08-171-34/+29
