xgettext doesn't handle escapes properly for bash

[Jakub Bogusz]

When using bash $"" translations, bash requires backslash-escaped
characters to be included with escapes in msgid/msgstr strings.
`bash --dump-po-strings` handles this properly, but xgettext doesn't
- it just omits backslash character.
Here is short test (using bash 3.0 and gettext 0.14.4):

$ cat xgt-test
#!/bin/bash
echo $"quoted \`"

$ bash --dump-po-strings xgt-test
#: xgt-test:3
msgid "quoted \\`"
msgstr ""

$ LC_ALL=C xgettext --omit-header -L shell -d -  xgt-test
xgt-test:3: warning: the syntax $"..." is deprecated due to security reasons; 
use eval_gettext instead
#: xgt-test:3
msgid "quoted `"
msgstr ""
