See http://www.maxim-ic.com/appnotes.cfm/appnote_number/1132
and
http://www.maxim-ic.com/quick_view2.cfm/qv_pk/1963
and use resistive voltage divider to scale the input down.

Hmm...cool. :-)
But, wouldn't I exceed their voltage ratings (+/-44V) when the
connections were "reversed"?

"Correct polarity" voltages from voltage divider:

50V -----+
|
.-.
| |100K
| |
'-'
+-------- 5V
|
.-.
| |11.1K
| |
'-'
|
0V -----+-------- 0V

"Reversed polarity" voltages from voltage divider:

0V -----+
|
.-.
| |100K
| |
'-'
+-------- 45V
|
.-.
| |11.1K
| |
'-'
|
50V -----+-------- 50V
