 At least you cannot write there. I think it is a bug, I don't see any use
 case.

 first) one is processed. E.g.:

 > GRASS 7.0.svn (2014)

 True, this is strange behavior. Pasting
 {{{
 print "a"
 print "bb"
 }}}
 prints just `a`. Note that second command is not really executed (tested
 with a = 1 and a += 1). While pasting
 {{{
 for a in [1, 2, 3]:
     print a
 }}}
 works as expected.

 history like in the Terminal) with the arrow up key. Using the arrow key
 causes the cursor moving up (see issue 1)

 You can use Ctrl and arrows, this will move you thought history. The
 question is if just arrow key wouldn't be better.

 I'm afraid that most of these problems are in the underlying wxPython
 PyShell.
