Subject: [PATCH] Minor fixes + alt code in 1990/baruch
Fixed formatting in README.md.
Add alt code based on authors' suggestion except that the string
replacement was not done because it seems like the output would be not
better but worse. There's a joke in the alternate code section of the
README.md file.

## To build:
- make all
+```sh
+make all
+```
## To run:
- echo 4 | ./baruch
- echo 7 | ./baruch
+```sh
+echo 4 | ./baruch
+echo 7 | ./baruch
+```
+
+## Try:
+
+```sh
+echo 2 | ./baruch
+echo 3 | ./baruch
+```
+
+Why is there no output?
+
+### Alternate code:
+
+[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) provided alternate code
+for users using Turbo-C or MSC, based on the authors' comments below, except
+that he did not change the `" #Q"` string as that showed worse looking output
+instead of improved output though he has no way to test the compilers in
+question. YMMV. Thank you Cody (though we all think [no
+one](https://en.wiktionary.org/wiki/no_one#Pronoun) [very
+few](https://en.wikipedia.org/wiki/0)
+[users](https://en.wikipedia.org/wiki/Microsoft_Windows)
+[here](https://www.ioccc.org) will need it :-) )!
+
+To compile:
+
+```sh
+make alt
+```
+
+Use `baruch.alt` as you would `baruch`.

This program demonstrates the claim that in C, any program
can be written using a single 'for' statement, as long as it is
long enough..
