That works as expected, thank you very much.

This problem is still vexing me. I believe there should be a simpler solution. In essence we are dealing with the following pattern:
Code:
[ ].*

a series of spaces
Code:
{code}

some code, with or without double / triple / etc spaces
Code:
[ ].*

(optionally) a series of spaces
Code:
// {comment}

(optionally) some comment with or without double / triple / etc spaces
The operation should be to leave 1, 3 and 4 alone and only replace the double spaces with single spaces from sub-pattern 2, the code. It should be possible to do this in a single sed statement.

Something like:
Code:
sed -e 's#\([ ].*\)\([a-z]*\)\([ ].*\)\(// .*\)#\1(s/  +/ /g \2)\3\4#' inputfile

Can someone give some pointers on how to do this?

ppi::token::quote::double

PPI::Token::Quote::Double(3)				User Contributed Perl Documentation			      PPI::Token::Quote::Double(3)

NAME

       PPI::Token::Quote::Double - A standard "double quote" token

INHERITANCE

	 PPI::Token::Quote::Double
	 isa PPI::Token::Quote
	     isa PPI::Token
		 isa PPI::Element

DESCRIPTION

       A "PPI::Token::Quote::Double" object represents a double-quoted interpolating string.

       The string is treated as a single entity, PPI will not try to understand what is in the string during the parsing process.

METHODS

       There are several methods available for "PPI::Token::Quote::Double", beyond those provided by the parent PPI::Token::Quote, PPI::Token and
       PPI::Element classes.

       Got any ideas for methods? Submit a report to rt.cpan.org!

   interpolations
       The interpolations method checks to see if the double quote actually contains any interpolated variables.

       Returns true if the string contains interpolations, or false if not.

   simplify
       For various reasons, some people find themselves compelled to have their code in the simplest form possible.

       The "simply" method will turn a simple double-quoted string into the equivalent single-quoted string.

       If the double can be simplified, it will be modified in place and returned as a convenience, or returns false if the string cannot be
       simplified.
