When interpreting a config value, the config parser reads in 1+ space
character(s) and puts -one- space character in the buffer as soon as
the first non-space character is encountered (if not inside quotes).
Unfortunately the buffer size check lacks the extra space character
which gets inserted at the next non-space character, resulting in
a crash with a specially crafted config entry.
The unit test now uses Java to compile a platform independent
.NET framework to output the test string in C# :o)
Read: Thanks to Johannes Sixt for the correct printf call
which replaces the perl invocation.
