+1.1 Multiline Indent
+
+There are several places where indent is necessary:
+
+ - if/else
+ - while/for
+ - function definition & call
+
+When breaking up a long line to fit within line width, we need a proper indent
+for the following lines.
+
+In case of if/else, while/for, align the secondary lines just after the
+opening parenthesis of the first.
+
+For example:
+
+    if (a == 1 &&
+        b == 2) {
+
+    while (a == 1 &&
+           b == 2) {
+
+In case of function, there are several variants:
+
+    * 4 spaces indent from the beginning
+    * align the secondary lines just after the opening parenthesis of the
+      first
+
+For example:
+
+    do_something(x, y,
+        z);
+
+    do_something(x, y,
+                 z);

 2. Line width
 
 Lines should be 80 characters; try not to make them longer.

 When comparing a variable for (in)equality with a constant, list the
 constant on the right, as in:
 
-if (a == 1) {

-    do_something();

 Rationale: Yoda conditions (as in 'if (1 == a)') are awkward to read.
 Besides, good compilers already warn users when '==' is mis-typed as '=',
