I think you might be having a shell quoting problem. The backslashes are swallowed by the shell if this is under sh. Try this: 

perl -wne 's/[^?]\47/\47\n/g; print' filename

This solution won't work if you have two consecutive (unescaped) apostrophes, or if the file has no newlines and is too long to read in memory.
