Evaluating
(compile "mkdir /tmp/newdir;\n cd /tmp/newdir;\n echo hi")
gets an emacs error
=> /tmp/newdir/: no such directory
and doesn't run the command. I hoped that no matter what the command
string contains that emacs would start it.
I suppose `compilation-start' attempts to set default-directory to the
cd it sees, but doesn't notice the command itself will create it.
A similar thing happens if you've got a hairy shell expression in the
cd,
(compile "cd ${FOO:-${BAR}};\n echo hi")
=> emacs error
I suppose in this case the expression is more than substitute-env-vars
understands.
I think if the apparent directory in a command doesn't exist then
compilation-start shouldn't try to use it.
