Thank you for the clarification! It would be nice to have that in the
documentation as well.

Probably better stick to the standard "If non-nil, restore...".

How about just "Restore standard layout for debug session (the layout we
get when session starts)." Or, even more concisely, "Restore the initial
GDB window layout"?

You can omit the "i.e.". Actually, even better perhaps just "window
configuration (layout)"? Similarly below.

How about "This arrangement depends on the values of `gdb-many-windows'
and `gdb-default-window-configuration-file'."

This is now no longer true.

Thank you,

P.S.: This time your patch somehow ended up hidden as
application/ocet-stream after the HTML part, instead of inline in plain
text.
