The following program:

-----------------------------------------------------------------------
#include <iostream.h>
#include <fstream.h>
#include <stdlib.h>
main() {
  char buffer[512];
  ifstream ifile("foo");
  if (!ifile)
    exit(1);
  while (!ifile.get(buffer,512,'\n').eof()) {
    char c;
    if (ifile.get(c) && c != '\n') {
      cerr << "input truncated\n";
    }
    cout << buffer << '\n';
  }
}
-----------------------------------------------------------------------


with file 'foo' as:

-----------------------------------------------------------------------
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
cccccccccccccccccccccccccccccccccccccccccc
dddddddddddddddddddddddddddddddddddddddddd

ffffffffffffffffffffffffffffffffffffffffff
gggggggggggggggggggggggggggggggggggggggggg
-----------------------------------------------------------------------


produces:

-----------------------------------------------------------------------
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
cccccccccccccccccccccccccccccccccccccccccc
dddddddddddddddddddddddddddddddddddddddddd







...
-----------------------------------------------------------------------

i.e. empty lines continue forever. It seems like get(), when given an empty
input line, sets the error state in the class which causes future get() calls
to do nothing.
