Initialization fails if process-environment is buffer-local (from envrc)

[axgfn]

If eshell-atuin-mode is run from a directory with a buffer-local process-environment, then ATUIN_SESSION does not get set globally and eshell-atuin never tries to reinitialize it. This can happen when using a package such as envrc, for example.

Currently I work around the problem by initializing eshell-atuin in a temporary buffer:

(with-temp-buffer
  (eshell-atuin-mode))

But another solution might be to store ATUIN_SESSION in a lisp variable and wrap each call to atuin in with-environment-variables.

Thanks for catching this. Implemented the latter suggestion in 24ac9fa.

However, manually running atuin in eshell still requires an environment variable... Which isn't strictly necessary for the functionality of this package, but still nice to have.

So for now I've left the global setenv together with with-environment-variables forms.
