Add 2014/vik/try.sh, update bugs.md, fix clobber

The bugs.md has more details on the bug I discovered when working on
2020/ferguson2. Even the usage in the try section (now in try.sh)
resulted in files that cannot be translated to English right.

The make clobber rule now removes *.raw instead of specific raw files.
This is important for clean up prior to updating the manifest.

Updated .gitignore.

+```sh
+echo 'No. I want chocolate!' | ./prog > chocolate.raw
+
+./prog e < chocolate.raw

+
+and get:
+
+```
+No. I want some chocolate!
+```
+
+but instead we get:

+```
+IT FHOCOLITE!
+```
+
+which is very wrong. If however one does:
+
+```
+echo IOCCC | ./prog > ioccc.raw
+
+./prog e < ioccc.raw
+```
+
+they will properly get:
+
+```
+IOCCC
