New Revision: 44742

URL: http://llvm.org/viewvc/llvm-project?rev=44742&view=rev
Log:
Fix a pretty big but subtle bug counting the number of newlines to emit.
This would cause us to emit different code (in -E mode) for these two files:

---
#define t(x) x

t(a
3)
---
#define t(x) x
t(a
3)
---

In one case, -E would print "a\n3", in the other it printed "a3".  Now
it prints "a3" for both.

This is part of PR1848.
