Improve wording for an NR paragraph (issue 259710043 by address@hidden)

Message:
I came across this rather mishapen wording in NR 4.6.2 – so I changed
it.

Description:
Improve wording for an NR paragraph

The paragraph from "Avoid (or reduce)" in spacing.itely
used 'for example' twice in a row. The description of the
'volta bracket' issue was unclear in terminology and phrasing.

 @item
 Avoid (or reduce) objects that increase the vertical size of a
-system.  For example, volta repeats (or alternate repeats) require
-extra space.  If these repeats are spread over two systems, they
-will take up more space than one system with the volta repeats and
-another system without.  For example, dynamics that @q{stick out} of
-a system can be moved closer to the staff:
+system.  For example, volta brackets for alternative repeat endings
+require extra space.  If these endings are spread over two systems, they
+will take up more space than if they are on the same system.
