5.1.44 groebner has some defects

[Oleksandr]

The entry "5.1.44 groebner" of online manual has the following at the end of example:

if (system("with","MP")) {groebner(i,10,"std");}
==> Singular error: MP (resp. MPT) syntax error : MPT: MPT tree has wrong syn\
   tax/structureSingular error: read: Error for link of type MPtcp, mode: fo\
   rk, name: child
defined(Standard::groebner_error);

which doesn't seem correct to me...

ps: in the Syntax header:

1. the following should be in separated lines:

   groebner ( module_expression, int_expression ) groebner ( ideal_expression, list of string_expressions )
   

2. duplication of

groebner ( ideal_expression, int_expression )

3. no analog for module_expression:

groebner ( ideal_expression, list of string_expressions ) 
groebner ( ideal_expression, list of string_expressions and int_expression )
