spaces...

[Paul Fontenot]

I have a file that for 1/2 the month has one space between every word, I use
this to split. However the other half the month it has two spaces in one
place and all the rest have one space.

Using s/ /#/g to change all spaces to # so I can use that for the split
doesn't work. How can I get the back to back spaces to be something else?
