Subject: [PATCH] Commit 1735f6f53ca19f99c6e9e39496c486af323ba6a8 started to
 escape all back-slashes which breaks case when lexicon translations contain
 substition and literals with eval-non-safe characters. E.g. these
 translations:
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

"[_1]foo\\n\n" => "[_1]bar\\n\n",
'[_1]foo\n' => '[_1]aěa\n',

got doubled back-slashes on the maketext() output.

This patch de-escapes escaped backslashes if the literal is compiled as
function argument.

Fixes RT #120457.
