errors.

cb9f4cb543 examples: fix handling of syntax errors 
The shell grammar does not allow empty statements in then/else part of
an if, but examples/test failed to catch the syntax errors from the
script it ran.  So exited with success anyway.

You would expect 'set -e' to suffice, but with bash 3.2 actually it
does not.  As a matter of fact, I could find a way to have this behave
properly:

    $ cat test.sh
    set -e
    cleanup ()
    {
      status=$?
      echo "cleanup: $status"
      exit $status
    }
    trap cleanup 0 1 2 13 15
    . $1
    s=$?
    echo "test.sh: $s"
    exit $s

    $ cat bistro.test
    if true; then
    fi

    $ /bin/sh ./test.sh ./bistro.test
    ./bistro.test: line 2: syntax error near unexpected token `fi'
    cleanup: 0
    $ echo $?
    0

Remove the set -e (or the trap), and tada, it works...  So we have to
deal with the error by hand.

* examples/test ($exit): Replace with...
($status): this.
Preserve the exit status of the test case.
* examples/c/bistromathic/bistromathic.test: Fix syntax error.

6135fdc152 examples: beware of portability issues with sh's trap 
On AIX 7.2, when invoking "exit 77", we actually exit with 127.  The
"cleanup" function, called via trap, received an incorrect exit
status, something described in Autoconf's doc.

df752784c2 examples: beware of portability issues with cmp 
As someone wrote nearly 20 years ago in Autoconf's documentation,
don't use cmp to compare text files, but diff.

58e79539fc c: don't emit an error message when the scanner returns YYERRCODE 
* data/skeletons/yacc.c (yyparse): When the scanner returns YYERRCODE,
go directly to error recovery (yyerrlab1).
However, don't keep the error token as lookahead, that token is too
special.
* data/skeletons/lalr1.cc: Likewise.

* examples/c/bistromathic/parse.y (yylex): Use that feature to report
nicely invalid characters.
* examples/c/bistromathic/bistromathic.test: Check that.
* examples/test: Neutralize gratuitous differences such as rule
position.

* tests/calc.at: Check that case in C only.
The other case seem to be working, but that's an illusion that the
next commit will address (in fact, they can enter endless loops, and
report the error several times anyway).
