The query history is stored within the client, so once the user stops
the client, it is gone. But yes, it would be useful to have some tool
that would allow you to see what's in there.
I could be a command (\showans ?) that would list all :ansXXX
variables, together with the query text and the size of the answer.
It would probably look ugly for very long queries, but could be useful
anyway.
I'm not sure if I'll be able to implement this feature any time soon,
as I'm very busy at the moment and going for a business trip in few
days.
In the meantime, I've applied your suggestions and moved the
sting-manipulating functions to stringutils. Also fixed a tiny bug.
Patch attached.
