 There is a special string concatenation function that accepts a `printf` alike
 format specifier and cats the formatted string to the specified string.
 
-        sds sdscatprintf(sds s, const char *fmt, ...) {
+    sds sdscatprintf(sds s, const char *fmt, ...) {
 
 Example:
 
-        sds s;
-        int a = 10, b = 20;
-        s = sdsempty("The sum is: ");
-        s = sdscatprintf(s,"%d+%d = %d",a,b,a+b);
+    sds s;
+    int a = 10, b = 20;
+    s = sdsempty("The sum is: ");
+    s = sdscatprintf(s,"%d+%d = %d",a,b,a+b);
 
 Often you need to create SDS string directly from printf format specifiers.
 Because `sdscatprintf` is actually a function that concatenates strings all
 you need is to concatenate your string to an empty string:
 
-        char *name = "Anna";
-        int age = 2500;
-        sds s;
-        s = sdscatprintf(sdsempty(), "%s wrote %d lines of LISP\n", name, age);
+    char *name = "Anna";
+    int age = 2500;
+    sds s;
+    s = sdscatprintf(sdsempty(), "%s wrote %d lines of LISP\n", name, age);
 
 You can use `sdscatprintf` in order to convert numbers into SDS strings:
 
-        int some_integer = 100;
-        sds num = sdscatprintf(sdsempty(),"%s\n", some_integer);
+    int some_integer = 100;
+    sds num = sdscatprintf(sdsempty(),"%s\n", some_integer);
 
 However this is slow and we have a special function to make it efficient.
 
@@ -286,14 +286,14 @@ Creating an SDS string from an integer may be a common operation in certain
 kind of programs, and while you may do this with `sdscatprintf` the performance
 hit is big, so SDS provides a specialized function.
 
-        sds sdsfromlonglong(long long value);
+    sds sdsfromlonglong(long long value);
 
 Use it like this:
 
-        sds s = sdsfromlonglong(10000);
-        printf("%d\n", (int) sdslen(s));

 Trimming strings and getting ranges

 This is an example of string trimming where newlines and spaces are removed

 Basically `sdstrim` takes the SDS string to trim as first argument, and a
 null terminated set of characters to remove from left and right of the string.

 Indexes can be negative to specify a position starting from the end of the
 string, so that -1 means the last character, -2 the penultimate, and so forth:
