For all you Unix gurus this should be run of the mill stuff but us 
Windows boys tend to get confused easily :)

How can I easily match occurrences of text along the lines of R&B and 
replace it with R&&B ?

The regular expression s/&/&&/g obviously replaces any occurrence of an 
ampersand with a double ampersand but I need to do a match so that it 
only replaces instances which have non whitespace on either side of it, 
ie \S&\S

I think I'm along the right lines but haven't had enough experience with 
regular expressions yet to 'finish the job'.

Hope you can help.
