[Bug-ed] g /RE/COMMAND-LIST not working ?

[積丹尼 Dan Jacobson]

We read

'(1,$)g /RE/COMMAND-LIST'
     Global command. Applies COMMAND-LIST to each of the addressed
     lines matching a regular expression RE. The current address is set
     to the line currently matched before COMMAND-LIST is executed. At
     the end of the 'g' command, the current address is set to the last
     line affected by COMMAND-LIST.

     At least the first command of COMMAND-LIST must appear on the same
     line as the 'g' command. All lines of a multi-line COMMAND-LIST
     except the last line must be terminated with a backslash ('\').
     Any commands are allowed, except for 'g', 'G', 'v', and 'V'. By
     default, a newline alone in COMMAND-LIST is equivalent to a 'p'
     command. If 'ed' is invoked with the command-line option '-G',
     then a newline in COMMAND-LIST is equivalent to a '.+1p' command.
