[DRE-maint] Bug#838940: rdtool: rd2man-lib.rb messes up with following DescListItem, if Description is multi-TextBlock

[Francesco Poli (wintermute)]

Package: rdtool
Version: 0.6.38-4
Severity: important

Hello again,
I think I found one more bug in rd2man-lib.rb .

Steps to reproduce with the attached trivial Ruby Document file:

  $ rd2 -r rd/rd2html-lib.rb -o desc desc.rd

Everything's fine. The resulting HTML file looks OK:

  $ sensible-browser desc.html

But, if I want to get a man page:

  $ rd2 -r rd/rd2man-lib.rb -o desc desc.rd

the resulting man page is:

  $ cat desc.1 
  .\" DO NOT MODIFY THIS FILE! it was generated by rd2
  .TH DESC 1 "September 2016"
  .TP
  .fi
  .B
  Term
  Description.

  More description..TP
  .fi
  .B
  Another term
  Another description.

which lacks the newline character before the second .TP
causing

  More description.
  .TP

to become

  More description..TP

Visualizing the man page confirms that the second DescListItem is not
rendered correctly:

  $ man ./desc.1


Is there anything I failed to understand?

If this is indeed a bug in rd2man-lib.rb, please investigate the issue
and fix it, and/or forward my bug report upstream.

Thanks for your time.
Bye!
