Travis-ci: added support for ppc64le

Document how to install ag.exe for Windows using winget

options: fix segfault when TERM or HOME isn't set

Change bro filetype support to zeek.

Add missing whitespace to test

Verify that ag works with no environment variables set.

This fixes the failing test.

* Add missing indentation (missed in c95d72f)
* Add missing newline at end of file (removed with 328afb2)

Regression from 3289ab8fba, if TERM isn't
set in the environment, getenv returns NULL which we shouldn't strcmp.
Similarly guard against using home_dir if it's null when looking for
global gitignore files.

This can be reproduced and tested with `env -i ./ag foo`.

Bring Ubuntu to 16.04 in Travis

Fix ignore patterns in subdirectories with leading slashes

Currenetly if you have an ignore file in a subdirectory "sub" with a pattern
like
    /ignorethis
The directory sub/ignorethis will be ignored if you run ag from
within sub, but it won't be ignored if you run it from sub's parent.
that is

    $ ag needle

will search files in sub/ignorethis, but

    $ cd sub
    $ ag needle

Will not.  This is a bug

It's common that you'd want edn files to show up in your clojure
searching.
