Using M-x shell in Emacs causes lossage in .bash_history.

I set HISTFILESIZE and HISTSIZE to large values in .bashrc
to not truncate the history file but comint.el disregards
my settings and truncates the history file used by bash.

The following patch make `comint-input-ring-size' customizable.
The type should be `integer' because this value is used by `make-ring'
to create the history ring.  The default value increased to 500
to be the same as the default value of HISTFILESIZE and HISTSIZE.

Looks reasonable enough to me.  Checked in, thanks.
