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.

To build:
make all
There is an alternate version, the original, that can't be compiled in modern systems but can be if you have an old enough compiler. See Alternate code below.
To use:
./isaak
Alternate code:
The original version of this code is in isaak.alt.c, with a minor fix so that it will compile. The original entry starts with the line:
main(){};
This works on some systems. Why? Note that #include <stdio.h> is given on
the last line. Why is this needed? Note the unusual calls to sprintf(3).
This version also relied on being able to define #define to something else and
using that macro for #define. This was fixed, however, so that you can at
least compile it in modern systems.
This version will not likely work on modern systems even though you should be able to compile it.
Alternate build:
make alt
Alternate use:
Use isaak.alt as you would isaak above.
Judges' remarks:
The program relies heavily on ASCII. Don't even think of running it on an EBCDIC machine.
Historical notes about the original entry
NOTE: If you named the file anything other than isaak.c, you had to
change the #include on line 6. This limitation has been fixed in
isaak.c and
isaak.alt.c by using the __FILE__ macro.
NOTE: The use of null comments to separate macros to construct different tokens
from a single macro (e.g., "O/**/O" creates either ++ or -- by defining
O to be + or -) may cause some strict ANSI C preprocessors to object.
NOTE: Most System V machines were not be able to execute this program correctly
due to the fact that BSD style systems have an sprintf(3) that returns a char *. Due to the above problems, we placed the output of this program in the
file isaak.output.txt. Since this was fixed, this file is
not strictly necessary, but we keep it for historical purposes (decoded as it
used to be uuencoded). See the
isaak.orig.c for the original source.
FYI: We are likely to be more strict about portability in the future.
