AFAICS compilation-directory is just used with recompile and it gets set by
M-x compile (through default-directory).

If I do M-x compile when default-directory has the value "/home/nickrob/" I
get:

-*- mode: compilation; compilation-directory: "/home/nickrob/" -*-

If I then do M-x dired to another directory /home/nickrob/C say, then
default-directory has the value "/home/nickrob/C", but when I do grep from
there e.g

Run grep (like this): grep -nH -e enum *.c

I get:

-*- mode: grep; compilation-directory: "/home/nickrob/" -*-

but I want to know the directory that grep was started from.  Why should I
be interested in the current value of compilation-directory here?
