If you write an example that generates a right-leaning triangle:
// Output:
// *
// **
// ***
Then it tests okay (I think the leading space is dropped from the target and the actual
output)
but it formats in the web godoc as:
*
**
***
instead of
*
**
***
That is, godoc eats the leading spaces.
More generally I wonder if the comment processing in examples should be handed off to
the standard go/doc comment processing and formatting. It already handles stripping an
*equal* amount of indent from pre blocks.
