TeX QUESTIONS

1) only ^^M (i.e., catcode 5) is changed to \par in state N

2) only ^^M (i.e., catcode 5) is changed to space

3) what if catcode of ^^M is changed? Theoretically it may have undesired effects, if it stays before \par - try to find an example which shows this (see http://tex.stackexchange.com/questions/259218/how-tex-reads-what-you-type)
