Add -0 and --print0 options. --null already existed but only worked for certain types of file searches. This fixes #326.
Update README. Ag uses Boyer-Moore now, not Boyer-Moore-Horspool.
Even though xz is mentioned in the build dependencies, some people can't seem to figure out how to install it. Fixes #467
Search stdin if stdin is a regular file. Fixes #476.
Spelling
Add --count/-c to count matches. This also counts on streams, but it's not very useful yet since lines with no matches don't print a zero. Anyway, it fixes #476.
