I have a quick question on the "proper" treatment of single quotes and
slashes.  Consider the following 2-line file:
c let's check this
     &        'and this'////)
When I run it through /lib/cpp on my machine (a NeXT running 2.1 and
GNU CPP version 1.36) I get the output (indented for clarity)
   testcpp.tmp:1: unterminated string or character constant
   # 1 "testcpp.tmp"
   c let's check this
        &        'and this' 
Is the complaint about line 1 correct? The complaint goes away if I
use the -traditional switch to /lib/cpp.  And how about the second
line?  Why are all the slashes and the parenthesis removed?  I've
tried this on several other machines (Sun, Iris, VAX/ULTRIX) and never
had this result.  I've looked at the GNU docs and haven't been able to
find anything explaining this behavior.
