CR line endings are escaped from PO files

[julen]

Take a PO file such as:

msgid ""
msgstr ""
"Content-Type: text/plain; charset=UTF-8\n"
"Content-Transfer-Encoding: 8bit\n"

msgid "Foo\r"
msgstr ""

msgid "Bar\r\n"
msgstr ""

and place it in a job's source_dir, specify the parse_pot parser and define some destination_language.

Run serge localize to run a localization step, hence generating the resources to be translated, as well as the localized resources.

Both the translated and the localized resources will contain escaped \r characters, i.e. \\r, while \n characters are kept as they are. One would expect \r characters to be kept as they are too.
