bug in field-string and field-string-no-properties

[Greg Hill]

There appears to be a bug in field-string and 
field-string-no-properties.  When (point) or the POS argument is at 
the first character of a field, the function returns an empty string. 
The following fragment of code, executed in the scratch buffer, 
illustrates the problem.

(progn
  (set-buffer (get-buffer-create "junk"))
  (erase-buffer)
  (insert "Test")
  (put-text-property (point-min) (point-max) 'field 1)
  (message "field-string at 1 = '%s'\nfield-string at 2 = '%s'"
  (field-string-no-properties 1) (field-string-no-properties 2)))
