cmd/gofmt: Inconsistent alignment of struct field values

[gopherbot]

by waters@google.com:

What does 'go version' print?

1.2, and using version from playground.

What steps reproduce the problem?

http://play.golang.org/p/tXDIgmPIky

What happened?

{
    Field:                     value,
    LongerField:               value,
    EspeciallyEvenLongerField: value,
    Field: value,
},

What should have happened instead?

{
    Field:                     value,
    LongerField:               value,
    EspeciallyEvenLongerField: value,
    Field:                     value,
},

Please provide any additional information below.

There appears to be logic in gofmt which avoids aligning long field values, but this is
inconsistent when a field is short after a long one.  See play link for other examples.

Comment 1:

This is not a bug. The code in gofmt aligns types of fields that belong to a "group" of
fields. A group of fields is terminated if the length ratio between the previous and the
next field declaration goes over a certain threshold.

Status changed to WorkingAsIntended.
