Improvements to source text

[Stephen Siegel]

This is all very minor but would improve the output a little.
In a for loop, the text associated to the increment expression extends one character beyond the expression, which usually means it includes the right parenthesis:

diffusion1_par.mmp line 25 proc 0 [MPI_Send@3->MPI_Send@1] "i++)" 

If it were not in a for statement, this would be correct because you want to include the final semicolon, but here it doesn't look good.

Also, for the conditional node associated to a for loop node, the source text includes the entire for expression:

diffusion1_par.mmp line 25 proc 0 [MPI_Send@1->MPI_Send@4] "for (i=0; i<count; i++)" [false] 

which I find a little confusing or inconsistent, because this statement is not executing the initialization or increment statements, it is only checking the loop continuation condition. Could we just include the condition here: "i<count" ?

Fixed. The source information is more accurate now.
