Remove some code

This commit removes the contribution of a user that we cannot trace to
gain their consent for the licence change.

After this commit the various IS_*() macros in the auto-generated file
conf_def.h may incorrectly return true if the supplied character has its
most significant bit set. The IS_*() macros should be able to correctly
handle 8-bit characters. Note that UTF-8 support is not a requirement.
