Update help_renameCrossReferences.sh:
- Do not relate separator character from source node when building
target node. They both, the source node and the target node, may
contain different information and even the procedure removed
here works well to nodes that have the same number of words,
that is not true for nodes that have different number of words.
When the target node has less words than source node there is no
problem, but when the target node has more words than source
node what separator do we use ? mmm... I don't like that so
replace source node with target node using an space to separate
words on target node, no matter if source node uses a white
space or a new line to separate words.
