Add 1995/savastio/try.sh and update bugs.md

The try.sh script demonstrates both positive numbers and input that is
not a number at all (comparing two different strings).

The bugs.md has a new INABIAF - negative numbers will hang the program.
It is not clear if another version should be added to gracefully handle
this but that can be decided another time. It is not a documented
feature so it might be called a bug to fix.

+### Bugs and (Mis)features:
+
+The current status of this entry is:

 ## To use:
 
 ```sh
 ./savastio
-# enter a number such as 100
+# enter a POSITIVE number such as 100
 ```
 
+NOTE: if you specify a negative number it will get stuck, showing no output. But
+what happens if you give a non-number?
+

 ```sh
-echo 42 | ./savastio
+./try.sh
