I only realized now that all of the above solutions have the condition backward: the first time through the loop I don't want to print an indentation. An outer routine has already typed a "header", like a number or a bullet, to the left and the print-head is now positioned at the indentation column at the time the subroutine is called. The first line must be printed without further indentation, but any subsequent lines will need indentation.

Interestingly, it was only when reading the Perl 6 syntax that this leaped out at me. For my purpose I'd need the NEXT phaser rather than the FIRST phaser. Thanks for the tip.
