iterate evaluate

[Juergen W. <wie...@fr...>]

Hi,

I would like to expand the iteration feature to the evaluate command
as I think this would be very useful.  I have attached a first naive
but generally working patch.  The problem is that the iteration is
not compatible to recursion.  Can it be fixed?  Is it worth the
effort?  IMHO a simple recursion detection would suffice.  I don't
see how to implement this right now in a way that still works after
an int_error(), though.

My use case: I have some more or less generic scripts with a
differing number of values d0, d1, ...  As I have to construct the
command line I'm stuck to the evaluate command.  I cannot even put
the iteration into a set command within the evaluated string.

BTW: AFAICS an int_error() leads to leakage right now as
check_for_iteration() simply discards (iteration_udv = NULL; ...)
instead of doing the correct deallocation.
