As I wrote earlier, the second sentence is inaccurate/incomplete.

> +@kindex set startup-quietly
> +@kindex show startup-quietly
> +This can also be enabled using @code{set startup-quietly on}.  The
> +default is @code{off}.  Use @code{show startup-quietly} to see the

Likewise.  Also, the text should say explicitly that the setting will
not affect any aspect of GDB behavior during the current session.

> +The directory in which this file appears depends on the host platform.

Once again, this has been already documented elsewhere in the manual,
and in more detail.  Please leave here just the cross-reference to
that place, and please call that file "startup file", for consistency
with the terminology there.

I think the doc string should mention that the setting has no effect
in this session.
