Features

Git who now reads and respects a .git-blame-ignore-revs file if present in the root of the repo (suggested in #10)
Git who now fully supports the "exclude" pathspec magic as defined in gitglossary(3). This allows you to ignore certain files by passing e.g. :!vendor/ or :!*.c (addresses #4)

Bug Fixes / Tweaks

Git who no longer panics when log.show-signature is set in the Git config (fixes #2)
Git who can handle leading whitespace in filenames (fixes #5)
"Terminator" (i.e. --) is now parsed properly from the CLI arguments, allowing deleted paths to be analyzed (fixes #7)
Commit "subject" no longer read from git log. It was previously ignored but not reading it entirely might fix #16
--diff-merges: first-parent no longer passed to git log invocation. This wasn't really needed and it turns out it is a relatively new feature of Git (version 2.31). This should help with #21
