Add 2015/schweikhardt/try.sh + format/typo checks

The bugs.md file has also been updated with a INABIAF section. One in
particular might be up to discussion and is easily fixed but it's not
clear yet if it should change so it's not done (for now?).

The issue above notwithstanding this entry should be complete.

+Hard requirements:
+
+* The platform must implement the `double` type as IEEE754-compliant 64-bit
+floating point numbers.  The 80-bit intermediate format used by x87 is
+considered as an violation of this. The code should print an error message on
+such platforms.
+
+* The program must start with the CPU / FPU in round-to-nearest mode.
+
+Soft requirements:
+
+* The compiler must respect `volatile`. The code is formatted to warn about
+that, though.
+
+* The printed result is only correct on little-endian machines. The program
+takes care to warn about this issue after printing an incorrect big-endian
+result. Error messages become garbled, though.

+The program assumes that `EOF` is `-1`. This can be fixed but at this time it is
+uncertain if it should be.

+The author also stated:

+
+While the program works best when bytes/characters are octets and the
+number of bits in a type is `sizeof(typ) << 3`, it will work correctly
+on 24-bit or 36-bit systems with 9 bits/byte, or systems where
+`sizeof(typ)` is 1 even for `int` and so on. On such systems, it will only
+use `8 * sizeof(typ)` bits per place. It does not work when `CHAR_BIT <= 7`.
