[Bug translator/10913] New: bad/misleading translator error message

["dsmith at redhat dot com" <sourceware-bugzilla@sourceware.org>]

Here's the test script:

====
function foo:long()                                                             
%{                                                                              
        THIS->__retvalue = 5;                                                   
}                                                                               
                                                                                
probe begin                                                                     
(                                                                               
        printf("%d\n", foo())                                                   
}                                                                               
====

Notice that the closing brace of the embedded-C function should be '%}', not
'}'.  Here's what you get when you run this script.

====
# stap -vg test.stp
parse error: expected '{'
	saw: junk '??THIS->__retvalue = 5;?}??probe begin?(??printf("%d\n", foo())?}'
at junk.stp:2:1
     source: %{
             ^
1 parse error(s).
Pass 1: parsed user script and 63 library script(s) using
83216virt/20040res/2396shr kb, in 150usr/50sys/201real ms.
Pass 1: parse failed.  Try again with another '--vp 1' option.
====

The translator's error message is completely confusing.  It points at the open
bracket, not at the lack of a proper closing bracket.
