Bug #4902: IO#each counts lineno

• Status: Closed
• Assignee: drbrain (Eric Hodel)
• Target version: 1.9.3
• ruby -v: ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-darwin10.6.0]

[bt (Bernd Homuth)]

The docs for IO#lineno state that:
lineno counts the number of times gets is called, rather than the number of newlines encountered.

However, IO#each also increases the lineno variable. Running this piece of code on a text file will print the last line number twice:

File.open('file.txt', 'r') do |f|
f.each_line do |l|
puts f.lineno
end
f.gets
puts f.lineno
end
