[DRE-maint] Bug#838938: rdtool: rd2man-lib.rb introduces spurious spaces around ((*emphasized*)) words in DescListItem Terms

[Francesco Poli (wintermute)]

Package: rdtool
Version: 0.6.38-4
Severity: important

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

Steps to reproduce with the attached trivial Ruby Document file:

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

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

  $ sensible-browser emph.html

But, if I want to get a man page:

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

the resulting man page is:

  $ cat emph.1 
  .\" DO NOT MODIFY THIS FILE! it was generated by rd2
  .TH EMPH 1 "September 2016"
  .TP
  .fi
  .B
  Emphasized [ \fItext\fP ]
  Text surrounded by emphasis inline.

which has additional unintended spaces before and after the emphasis,
causing

  [\fItext\fP]
  
to become

  [ \fItext\fP ]

Visualizing the man page confirms that the the word [text] is displayed
spaced:

  $ man ./emph.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.
