While not strictly necessary, replacing the two ASCII tab characters in the markdown copyright comment makes it easier to detect problematic TAB indentation within markdown files. After this commit, only 90 markdown files have leading ASCII TAB characters. And again, while not strictly necessary, we can consider running expand on those 90 markdown files to see what effect that might have on the HTML files they produce. Replace leading ASCII TAB characters with multiples of 8 ASCII SPACE characters (the default action of the `expand(1)` tool) might have an negative effect on some HTML formatting where **hack-a-round** formatting was attempted to fix broken indentation caused by problematic ASCII TAB characters. Think of this as a baseline for evaluating leading TAB characters within markdown files. TODO: Consider either using `expand(1)` to replace leading ASCII TAB characters with multiples of 8 ASCII SPACE characters AND/OR modifying the appropriate `bin` tool to convert leading ASCII TAB characters into multiples of 8 ASCII SPACE characters.

Judges' remarks:
The Judges believe that this is the best one line entry ever received. Compile on a UNIX system, or at least one using a C implementation that fakes it. Very few people are able to determine what this program does by visual inspection. I suggest that you stop reading this section right now and see if you are one of the few people who can.
Several points are important to understand this program:
-
What is the symbol
unixand what is its value in the program? Clearlyunixis not a function, and sinceunixis not declared to be a data type (such asint,char,struct foo,enum, ...) what mustunixbe? -
What is the value of the symbol
"have"? (hint: the value is NOT 4 characters, or'h', or a string) Consider the fact that:
char *x;
defines a pointer to a char (i.e. an address), and that the = assigns
things of compatible types. Since:
x = "have";
is legal C, what type of value is "have"?
- Note that the following expressions yield the same value:
x[3] *(x+3) *(3+x)
since addition is commutative. What can be said about this value?
3[x]
David Korn's /bin/ksh provides us with a greatly improved version of the /bin/sh. The source for v7's /bin/sh greatly inspired this contest.
