Yes.

Yes.  (Sorry, I assumed this rule was known to all and didn't
have to be stated.)  Also, I would say any number of \,newline
pairs, from zero on up.

Yes.

Yes, except that I would add that /*...*/ comments might (and
often do) occur on a single line.  But yes in the sense that they
will include any embedded newlines.

Yes.

Yes.  (Usually these are called character constants rather than
strings.)

Yes.  Technically if a string or character constant isn't closed
before the next (unescaped) newline then that is undefined
behavior.  In other words the input is not lexically well-formed,
and so may be handled as you see fit (expecting that the handling
is sensible rather than something nutty).

Yes.  I should add, the C standard wants source files to end only
after a final (unescaped) newline, so EOF anywhere other than at
the beginning of a line might be flagged as an error.  But doing
nothing or adding a final newline if one is missing is okay too.

Yes.

Yes.

Yes.  (And similarly for more than one \,newline pair between the
two initial / characters.)

> c3) Since \ cannot be escaped, \,\,newline,A (0x5c,0x5c,0x0a,0x41)
      is really \,a (0x5c,0x41).

Yes (presuming you meant 'A' and not 'a' at the end there).  Also
note that context matters:  inside a comment, \,\,newline,A is
just gobbled up;  outside a comment, \,\,newline,A should result
in \,\,newline,A in the output, i.e., the \,newline pair should
be preserved in the output.

Yes.

Yes.

Yes.  (I take the output on the second line as having a space in
between the second " and the [space].)

Yes.

I am looking forward to seeing your next version.
