The rst2po tool takes care of this translation.

This will fail anyhow, since you will get the string as it was compiled,
ie.  compiled on linux will result in a #10, on windows in a #13#10.

This is not true.

The solution is very simple; have a look at the existing gettext support.
(unit gettext)
You can transform the resourcestrings at program startup as part of the
gettext support. This way you can store whatever you want in the
resourcestring. At program startup, when localizing, the strings are
translated and transformed on the fly...

See also the programmer's manual, the resource string support is covered

No, because normally you don't need this.

It doesn't do any as far as I know.
