Wrong addresses in the reports

[Thanatermesis]

On this sample text:
_ _ _ _ englich _ _ writted _ _

atdtool reports:
$ atdtool /tmp/english-sample.txt
/tmp/english-sample.txt:1:8: Spelling "englich"
suggestions: english, English, enrich, Anglice
/tmp/english-sample.txt:2:1: (?) Spelling "englich"
suggestions: written, writhed, witted, gritted

The first report says that is in column 8 but it is on the number 9, so 1:9
The second one says that is the first column of the second line, but we still on the first line, and in column 21, so 1:21

This makes atdtool uncompatible with other external tools, like the atdtool checker in the vim plugin "syntastic"
