Summary:                    error/warnings for difficult if() statement in AEL
Description: 
I have such code in AEL config:
if ($[${LEN(${var})} = 0] | $[${LEN(${var})} = 4] | $["${var}" = "value"])
{

It is successfully converted into dialplan command, that's work like
expected:
GotoIf($[$[${LEN(${var})} = 0] | $[${LEN(${var})} = 4] | $["${var}" =
"value"]]?6:8)


But error messages are produced in log:
[Mar 20 17:30:45] WARNING[2638] ast_expr2.fl: ast_yyerror(): file
/etc/asterisk/extensions.ael, line 57, columns 7-7, if expr
'$[${LEN(${var})} = 0] | $[${LEN(${var})} = 4] | $["${var}" = "value"]':
syntax error: syntax error, unexpected '<token>', expecting $end; Input:
$[${LEN(${var})} = 0] | $[${LEN(${var})} = 4] | $["${var}" = "value"]
  ^
[Mar 20 17:30:45] WARNING[2638] ast_expr2.fl: If you have questions,
please refer to doc/tex/channelvariables.tex in the asterisk source.
[Mar 20 17:30:45] WARNING[2638] ael/pval.c: Warning: file
/etc/asterisk/extensions.ael, line 57-59: The expression '$[${LEN(${var})}
= 0] | $[${LEN(${var})} = 4] | $["${var}" = "value"]' is redundantly
wrapped in '$[ ]'.

seems like AEL parser can not to produce an error messages in such cases.
