Subject: [ruby-talk:10655] Re: Word wrap algorithm

Thanks for the start on the ASCII word wrap algorithm.  I changed it around 
a little to take into account tabs and to keep formats for empty lines 
between paragraphs and to leave a line that is shorter than the word wrap 
size and has a "\n" on the end intact.  You'll see the similarities to yours.

puts $<.read.gsub(/\t/,"     ").gsub(/.{1,50}(?:\s|\Z)/){($& + 
5.chr).gsub(/\n\005/,"\n").gsub(/\005/,"\n")}

wraps everything to at most 50 characters wide.
