(Info-fontify-node): Fixed hiding of *note references

Browse Source 
with embedded file names like (xxx.yyy).
Avoid making any lines visibly longer if hiding newlines inside
note references by wrapping line after references if it contained
a newline (unfortunaly this makes more lines appear "shorter").
Properly reindent multi-line menu entry descriptions.
