Subject: [PATCH 01/12] Fix 2013/endoh3 for shellcheck

Even though the author used 'cat file | ...' use the form './endoh3 <
file | ...' rather than have to disable the shellcheck warning about
useless cat. In some cases using it does simplify the command but not
much in this case (though I still say there's no such thing as a useless
cat: besides offering endless joy and wonder how else would we EVER know
that the Earth is not flat if we didn't have cats to push everything off
flat surfaces? :-) .. I mean besides lots of science to back it up, that
is :-) ).

Subject: [PATCH 02/12] 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.

Subject: [PATCH 09/12] Improve 2015/howe/try.sh and fix make clobber

The make clobber rule now removes *.tmp instead of just specific .tmp
files.

Updated .gitignore: removed the foo.tmp globs and added *.tmp.
