The try.sh script cannot be modified to prompt the user to run commands
as the other scripts (or at least one, diff.sh) make use of tail(1) on
the output. The script diff.sh however can have that and it has been
done.
Minor fixes in display in slflen.sh.
The demo.sh was renamed try.sh to be like the other entries.
The new script diff.sh runs some commands that I had previously added
(to demonstrate the entry) but which would be better in a script.
Renamed sflen.sh (for sparkline file length) to be slflen.sh (for
sparkline file length also).
Updated bugs.md - added more features that the author noted.
Format/typo check README.md file.
This should complete the review of 2013/dlowe.
