What is happening is that the variable location (created in C) is being
shared by all buffers until a buffer local value is "primed" in a buffer
with a `setq' invocation.
How does one correctly create a buffer local variable in C? What I have
at the moment is:
DEFSYM (Qcomment_depth_hwm, "comment-depth-hwm");
DEFVAR_LISP ("comment-depth-hwm", Vcomment_depth_hwm,
doc: /* Buffer position below which the `comment-depth'
property is valid. */);
Vcomment_depth_hwm = make_number (1);
Fmake_variable_buffer_local (Qcomment_depth_hwm);
This is clearly inadequate, of itself, to create a buffer local variable.
