Indeed, the problem is that the dynamic binding of project-root is
created inside the `interactive' spec and that spec is not run in the
proper lexical environment (it is run in lexical mode, but in an empty
lexical environment).

A bug in Emacs.  Should be fixed on the trunk now.

BTW, please add an "ack--" prefix to your `project-root' var: all
`defvar'd variables should have such a prefix.

Hello Stefan,

I got a bug report on ack.el (https://github.com/leoliu/ack-el/issues/1)
when running ack.el uncompiled.

The steps to reproduce:

1. wget https://github.com/leoliu/ack-el/raw/master/ack.el
2. Emacs -q -l ack.el
3. M-x ack

file-name-nondirectory: Symbol's value as variable is void: project-root

Could you help me understand what is wrong here? It seems when
uncompiled project-root is not treated as a special variable.

Thank you,
Leo
