Prevent variable substitution with # nosubst will delete the annotated line

Describe the bug

Since breaking change 4023f7f8 the option # nosubst in function tbc_envsubst is not working as documented any more.

Expected behavior

Variable substitution can be prevented by appending # nosubst at the end of any line. So the line will not be changed.

Actual behavior

Since Version 7 all lines with an appended # nosubst are deleted after tbc_envsubst function.
