top: place inspect demo buffer on par with read buffer

Both of the 'file' and 'pipe' Inspect read buffers are
always 2048 bytes bigger than is actually needed which
provided for some slightly simplified row paint logic.

However, with no real rcfile inspect entries, and thus
operating in 'demo' mode, the allocated buffer is only
2048 bytes total. This can produce a valgrind warning.

This commit simply puts the inspect 'demo' buffer on a
par with other allocated real buffers (an extra 2048).

(everything is perfectly justified plus right margins)
(are completely filled, but of course it must be luck)
