WCPS1.0_Missing operator '+' in request from Petascope console

[Bang Pham Huu]

From a request on group ​https://groups.google.com/forum/#!topic/rasdaman-users/xA6nlD2M-sA

for c in (Timeseries)
return encode (    
(( ( c[ansi("2016-01-01")]).red - ( c[ansi("2016-01-01")]).nir)  
/ 
 (  ( c[ansi("2016-01-01")]).red + ( c[ansi("2016-01-01")]).nir  ))

this can work correctly if request directly from WCPS URL

localhost:8080/rasdaman/ows?service=WCS&version=2.0.1&request=ProcessCoverages&query=for c in (Timeseries)return encode ((( ( c[ansi("2016-01-01")]).red - ( c[ansi("2016-01-01")]).nir)  /  (  ( c[ansi("2016-01-01")]).red + ( c[ansi("2016-01-01")]).nir  )),  "png")

but not if request from Petascope's console.

due to in parsing from Petascope's console, it missed the '+' in request.

for c in (Timeseries)return encode ((

( ( c[ansi("2016-01-01")]).red - ( c[ansi("2016-01-01")]).nir)  

/ 
 (  ( c[ansi("2016-01-01")]).red  *MISSING*  ( c[ansi("2016-01-01")]).nir  )),  
"png")

and throw an exception

It works also with WCPS1.5 in WCPS Request by URL, need to check the result from Petascope's console with WCPS1.5 also.
