Subject: [PATCH v2 06/12] grep: rewrite an if/else condition to avoid duplicate expression

From: Nguyễn Thái Ngọc Duy <[email-masked]>
Date: Sat, 25 Jun 2016 07:22:32 +0200

"!icase || ascii_only" is repeated twice in this if/else chain as this
series evolves. Rewrite it (and basically revert the first if
condition back to before the "grep: break down an "if" stmt..." commit).
