From 12ae6779332181432a7feda740735ffa5bb3d32d Mon Sep 17 00:00:00 2001 From: Daniel Santos Date: Thu, 4 Oct 2012 17:15:10 -0700 Subject: [PATCH] kernel-doc: don't mangle whitespace in Example section A section with the name "Example" (case-insensitive) has a special meaning to kernel-doc. These sections are output using mono-type fonts. However, leading whitespace is stripped, thus robbing a lot of meaning from this, as indented code examples will be mangled. This patch preserves the leading whitespace for "Example" sections. More accurately, it preserves it for all sections, but removes it later if the section isn't an "Example" section.
