That is not correct. Reading the manual is not sufficient to ensure a
solution is 100% correct. There can be always corner cases that only
somebody who is familiar with the awk internal can be sure about.
Otherwise, there wouldn't be so many partially correct solutions
floating no the web.

See, if this is disagreed by the next reply.
