Fix missing risky mark on hook variable
Add `--unix_mode` option for gjslint exec [#348]

Specify `--unix_mode` option, an error message will be output in UNIX
format. This format is including file-name every lines.

Previously, the error message did not include file-name. I think good
that specify this option.

[Fix #363] Load find-func at runtime

We need find-func at runtime for find-function-regexp-alist.  I
overlooked this when refactoring the dependencies, because the f******
stupid byte compiler didn't warn about the add-to-list call.

This partially reverts commit c8babdbb536852ac49978935d9585e7e18a77980.
