Subject: [PATCH 1/4] Documentation: move diff.wordRegex from config.txt to
diff-config.txt
19299a8 (Documentation: Move diff.<driver>.* from config.txt to
diff-config.txt, 2011-04-07) moved the diff configuration options to
diff-config.txt, but forgot about diff.wordRegex, which was left
behind in config.txt. Fix this.

Subject: [PATCH 3/4] diff: rename "set" variable
Once upon a time the builtin_diff function used one color, and the color
variables were called "set" and "reset". Nowadays it is a much longer
function and we use several colors (e.g., "add", "del"). Rename "set" to
"meta" to show that it is the color for showing diff meta-info (it still
does not indicate that it is a "color", but at least it matches the
scheme of the other color variables).

Subject: [PATCH 4/4] submodule: display summary header in bold
Currently, 'git diff --submodule' displays output with a bold diff
header for non-submodules. So this part is in bold:
diff --git a/file1 b/file1
index 30b2f6c..2638038 100644
--- a/file1
+++ b/file1
For submodules, the header looks like this:
Submodule submodule1 012b072..248d0fd:
Unfortunately, it's easy to miss in the output because it's not bold.
Change this.
