Bug#316501: cdebconf: trailing characters when displaying long multiline descriptions

[Tamas Pal <folti@balabit.hu>]

Package: cdebconf
Version: 0.74.2
Severity: minor
Tags: patch

When cdebconf displays a template with multiline descriptions, the last
n(n== the number of of newlines in the original extended_description) 
characters of the description will be shown after it. 
The origin of the problem is the remove_newline function in template.c, which
doeasn't apply a \0 after the truncated string.
