Problems:
1. Without a message, users don't find 'last'
2. Showing a message for every error clutters output.
This tries to address these issues by:
1. Only showing the message when other feedback has not been provided and
'last' would not usually be helpful. This will require ongoing tweaking.
For now, all commands except 'compile' display the message. 'update' could
omit the message as well, but perhaps knowing about 'last' might be
useful there.
2. Including the exact command to show the output:
last test:compile
and not just
last <task>
3. Highlighting the command in blue for visibility as an experiment.
Review by @ijuma and @retronym, please.
`docSetting` has been updated to do both Scaladoc and Javadoc. In
Scala/Java hybrid projects, the output docs are rebased to `scala`
or `java` sub-directory accordingly. But for pure scala or pure java
projects the subdirectories aren't added to becompliant with user
expectation as much as possible. We do hybrid mode iff both *.scala
and *.java files exist; other doc resources (package.html, *.jpg etc.)
don't influence the decision.
