Searching info files using info browser

[Gavin Smith]

Hello,

I have a couple of long-standing annoyances when searching info
documentation. I have looked through the documentation but haven't
been able to do the following:

* Edit previous searches made with "s" or "/". If I press the up key,
I get a message "[`ESC O a' is invalid]". Pressing Alt-P gives the
message "[`ESC p' is invalid]".
* Skip the current screen when moving between results with "}" and
"{". This is like the "-a" option to the less pager.

Are these possible, or if not, could this functionality be added?
