Good find.
A general rule for a name used to refer to a configuration variable
the C code ought to be
- if it is used to match what the system gave us, make sure we use
all lowercase for the first and the last component and match with
strcmp(), not with strcasecmp().
- if it is used to update, make sure we use the canonical spelling,
if only for the documentation value.
