Subject: Slight tweak to last change -- parse MODE value even when there's no SCAN_FORMATS... 
X-Git-Url: http://git.rot13.org/?p=zxing.git;a=commitdiff_plain;h=a054d60a8432f1635518b04117127e06283fe131

Slight tweak to last change -- parse MODE value even when there's no SCAN_FORMATS. Also be extra paranoid about other call to String.split()
