#325 rexxref 2.3 CALL and chapter 11 should document namespaces

[Josep Maria Blasco]

In 2.3, "Call name" should be expanded to "( call [namespace:]symbol" | call string)".

Additionally, in chapter 11, the trapname of CALL ON currently does not support namespaces. My impression is that it should. Otherwise, the fact that they cannot be used should be documented.

Namespaces should also be mentioned in 7.1 "Syntax", and in 1.11.1 "Terms and Expressions". The nomenclature should be adjusted so that it is the same (currently, it's "stringorsymbol" in one place, and "function_name" in the other).

[Josep Maria Blasco]

This patch adds a mention to namespaces in 7.1, with a new syntax diagram, and fixes extra blanks in the paragraph that starts with "There can be any number of expressions...".

As a convenience, I'm also attaching the new svg trunk/rexxref/en-US/images/bif/function_name.svg.

Thank you, Jon!

This patch builds over the previous one. It includes fixes for sections 2.3 CALL and 1.11.1 Terms and Expressions, and also a small fix for 7.1, and the missing svg files.
