[Gllug] simple sed question

[robin.c.smith at bt.com]

To answer my own question ( after reading a bad man page - always RTFM ),
the following sed works on my Sun 5.6 box, ^M is ctrl-M:-

Put this in a file e.g. a.sed

/^M$/{
  N
  s/^M\n//g
} 

and then run 

sed -f a.sed filetomodify

GNU sed supports a newline in the regexp, as do some other 
implementations, and has no maximum line length so you can match across 
as many lines as you care to.
