Minor fixes in the help messages

* If the text to cite where the problem occurred is "\n", prettyprint
   somethign a little nicer so that it's clear that we're talking
   about the end of line
 * Add a missing help message ("ini file:unknown field"), and display
   it a little better (i.e., show the erroneous field, not a
   misleading "end of line" marker)
 * It's "OpenIB", not "Open IB"
