errors/fmt: don’t indent first line of detail in absence of message

Newlines within regular messages are now also indented
in detail mode.

The colon ‘:’ is still strictly interpreted as a separator of
the regular message and the detail part. This means that
there is no colon after the first line of a detail-only message.

The indenting formatter is now always called in detail mode.
This does not show any differences in the benchmarks
and also simplifies the codes.

exp

This subrepository holds experimental and deprecated (in the old directory) packages.

The idea for this subrepository originated as the pkg/exp directory of the main repository, but its presence there made it unavailable to users of the binary downloads of the Go installation. The subrepository has therefore been created to make it possible to go get these packages.

Warning: Packages here are experimental and unreliable. Some may one day be promoted to the main repository or other subrepository, or they may be modified arbitrarily or even disappear altogether.

In short, code in this subrepository is not subject to the Go 1 compatibility promise. (No subrepo is, but the promise is even more likely to be violated by go.exp than the others.)

Caveat emptor.
