doc: use the new jimtcl syntax for 'expr'

With jimtcl 0.81 the syntax of the TCL command 'expr' requires the
multiple arguments to be within curly brackets.

Update the examples in the documentation to follow the new syntax.
While there, split one example to avoid it to exceed the line size
during pdf document generation.
