Thanks to everyone for your help!

Unfortunately -r doesn't seem to be valid with the Solaris Sed:

$ echo 123456789 | sed -r ':a s/([0-9]+)([^,]{3})/\1,\2/;ta'
sed: illegal option -- r
Usage:  sed [-n] script [file...]
        sed [-n] [-e script]...[-f script_file]...[file...]
But using GNU sed:

$ echo 123456789 | sed -r ':a s/([0-9]+)([^,]{3})/\1,\2/;ta'
Which is a pity really, because I agree that in statements such as this it is much clearer to be able to drop the back slashes.
