Subject: [PATCH] .errdef/.errndef with or without custom message

GetErrText is not usable 'cause it overwrites StringBufferEnd. So we
must append text to StringBufferEnd. Not all checks as in GetErrText
are performed. So we have side effect: message can be in angle
braces or in quotes too.

Fixes #184.
