[DRE-maint] Bug#716916: ruby-gettext: rxgettext doubles the backslashes in newline '\n' characters

[Francesco Poli (wintermute)]

Package: ruby-gettext
Version: 2.3.9-1
Severity: normal

Hello!
First of all, thanks a lot for fixing the bugs I have previously
reported (#684182, #684184, and #692487)!

I noticed something new in rxgettext, and it looks like a newly
introduced bug.

Let's again consider the test case described in bug #684182 [1].

[1] http://bugs.debian.org/684182

If I generate the corresponding .pot file with rxgettext,
I get the following result:

  $ rxgettext --copyright-holder="Francesco Poli" \
    --package-name=myapplication --package-version=0.1 \
    --msgid-bugs-address="address at example.com" \
    myapplication.rb -o myapplication_RXGETTEXT.pot
  $ cat myapplication_RXGETTEXT.pot

  #: myapplication.rb:24
  msgid "Hello everybody!\\n"
  msgstr ""
  
  #: myapplication.rb:27
  msgid "You are running an internationalized Ruby program.\\n"
  msgstr ""
  
  #. %d is the number of already printed messages
  #: myapplication.rb:31
  msgid "You have already seen %d translatable messages.\\n"
  msgstr ""
  
  #: myapplication.rb:33
  msgid "Is this message # 3 or # 4 ?\\n"
  msgstr ""
  
  #: myapplication.rb:35
  msgid "OK, I am tired...\\n"
  msgstr ""
  
  #: myapplication.rb:37
  msgid "Goodbye!\\n"
  msgstr ""


Why all the newline '\n' characters are produced with doubled
backslashes (as "\\n")?
I do not see this behavior, if I use xgettext (from the gettext
package).

I think this is a bug in rxgettext.
If you agree, please fix it and/or forward this bug report upstream.

Thanks for your time!
