Re: root_hist

Hello Axel,

If users can change the size of history without re-compiling, (e.g. by editing .rootrc)
it will be better approach.

# like as .bashrc
# export HISTSIZE=1000
# export HISTFILESIZE=1000

When I run ROOT many times in batch mode from a shell script, default 500 lines is not enough.

Sincerely,
