apparent clearsigning bug

[Greg Troxel]

This is with pure 0.9.1 (plus export-dynamic fix to compile) on
FreeBSD 2.2.X.  I believe that final input lines without newlines are
at least sometimes handled incorrectly.

I found (by accident) that a message with a final line with a space
but no newline produced a clearsig that didn't verify.
Here is an example; the file contains the words
 this is a sig test
on one line followed by a \n and then a ' ', and no trailing \n.


fnord gdt 84 ~/.gnupg > cat sig-test-1
this is a sig test
 fnord gdt 85 ~/.gnupg > ed sig-test-1.asc

BAD SIGNATURE


I note that the output has a ' ', but no \r.

A different file with a second line with just a ' ' but a proper
trailing \n has instead a normal empty line in the signature.
