Glad someone is using CONFIG_USE_DEFAULT_ENV_FILE :) And thanks for
reporting this.

Hm, yeah, that should work. But I wonder if it would make more sense to
ensure tr always gets a final newline (which then gets translated to a
nul byte, which in turn gives the trailing 0x00). Something like (untested)
define filechk_defaultenv.h
( { grep -v '^#' | grep -v '^$$' ; echo '' ; } | \
tr '\n' '\0' | \
sed -e 's/\\\x0\s*//g' | \
xxd -i ; )
