Hello Rob,

I have a script that uses ed to generate C string definitions from nroff output.
It makes essential use of global substitutions with a newline as the
replacement text, e.g.,
g/^##*/s/#*/\
/
This functionality is no longer available as of version 1.14 of GNU ed. Is there
a work-around for this?
This functionality was removed from GNU ed because inside a global
command the meaning of the escaped newline becomes ambiguous. The POSIX
standard documents it:
http://pubs.opengroup.org/onlinepubs/9699919799/utilities/ed.html
"A line can be split by substituting a <newline> into it. The
application shall ensure it escapes the <newline> in the replacement by
preceding it by <backslash>. Such substitution cannot be done as part of
a g or v command list."
The workaround is to use 'sed' to split a line in this way. I think sed
does not have this problem because it does not need a 'global' command.
Best regards,
Antonio.
