bug#4308: 23.1.50; patch: fix `eshell-history-file-name'

[Leo <sdl.web@gmail.com>]

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

The attached small patch makes eshell-history-file-name more robust. For
example, I accidentally set eshell-directory-name to ~/.emacs.d/shell
without a trailing / and the history was written to
~/.emacs.d/shellhistory.
