Patch is still line-wrapped in at least one place, and patch 2/2 is
wrapped in several.
Based on format and the headers, it doesn't look to me like you're
using git-send-email. Really, git-send-email will make your life much
simpler.
Feel free to send me some test patches off-list so we can figure
out your mailer problems.
