Subject: [PATCH] 1989/fubar updates

Format fix the README.md file including removing some '\'s at end of
lines (in the remarks).

Document feature that if the arg is a large number or < 0 (the latter of
which I discovered a few minutes ago as I was working on this) it will
enter an infinite loop trying to compile code that has syntax errors.
This was noted by the judges at the time so it is not a bug but a
feature. This has been added to the bugs.md and the README.md file.

+### INABIAF - it's not a bug it's a feature! :-)
+
+If you use either `fubar` or `ouroboros.c` (it's executable, see below) with a
+number < 0 or larger than, say 20, it's very likely that the program will turn
+into an infinite loop trying to compile code with syntax errors.
 
 ## Judges' remarks:
 
-Run this with a single digit argument (or wait a long time).
+Run this with a single digit argument (or wait a long time and risk an infinite
+loop as described above).
 
 The blank line at the beginning of the source is mandatory.
 Do you know why?
 
-NOTE: don't try running `ouroboros.c` (note that it's executable)
-directly with an arg as it'll turn into an infinite loop. The same will happen
-with larger numbers.
-
 NOTE: the file `ouroboros.c` is created by the program itself so this is why it
 is not in the repository.

+
+Specifying too large a number (or < 0) to either `fubar` or the source code file
+(it's executable) that it generates will cause the program to enter an infinite
+loop, trying to compile code with syntax errors. At least in one system any
+number larger than 20 did this.
