Term::ReadLine extra newlines?

rjray has asked for the wisdom of the Perl Monks concerning the following question:

Has anyone noticed any problems with either Term::ReadLine itself, or one of the implementation classes, inserting extra newline characters when displaying prompts? This only recently happened, after upgrading my Linux box to Fedora Core 5. Checking against CPAN, I have the latest version of T::RL, and of T::RL::Perl, etc. I cannot find anything in the manual pages to suggest that this is an accidentally-enabled "feature".

Hmm... that bug in the most recent version was believed to be Win32-specific. I'm not sure they've been able to nail it down yet... if the assembled monks could work out why the hell it's happening, it would be helpful.	[reply]

It sounds to me as if a bare CR, which should just reposition the cursor at the start of the current line, is being interpreted as a real end of line, thus, starting again on the next line. Could that be what is going on?	[reply]

I doubt it. There are no CRs in the strings I'm passing to `$term->readline($prompt)`. It has to be coming in somewhere within `readline` itself. `--rjray`	[reply]
