RE: setenv and find-file

Peter,

Sorry if I was too terse.

I see a problem when M-x find-file is expanding ${VARIABLE} but not taking it from the newly defined environment variable. Everything else picks it up (I presume just via fork/exec).

I hope this script is clearer.

In shell:
    $ echo ${VARIABLE}
    /a/very/long/path
    $ emacs &
Inside emacs:
    C-x C-f ${VARIABLE}/to/work                <== Finds "/a/very/long/path/to/work".
    (setenv "VARIABLE" "/shorter/path")
        => "/shorter/path"
    M-! echo ${VARIABLE}
    "/shorter/path"
    M-x shell
In shell inside emacs:
    $ echo ${VARIABLE}
    "/shorter/path"
Back in emacs:
    C-x C-f ${VARIABLE}/to/Grandmothers/house
This finds the file "/a/very/long/path/to/Grandmothers/house", where I sort of expect it to find "/shorter/path/to/Grandmothers/house".

If the majority of cooking accidents happen in the kitchen, then why don't we just cook in other rooms?

Can you describe, in other words, maybe in more than one sentence, what the cited line is trying to express? I only understand "station"...

We have to expect it, otherwise we would be surprised.
