I need to be corrected if wrong but I see that you are reading the entire file into a string and not reading one line at a time, hence chomp would result in only chomping at the end of the file and not every line end as you intend to...I haven't tested it anyways. This an initial look at it.

(Update): After ack clarification, and I always have been having a trouble with scalar and list contexts, I would say I retract my observation since I thought the $firstline is the same as the @firstline, thanks ack and excuse my ignorance for I am still learning too.
