• ext/emacs/puppet-mode.el (puppet-comment-line-p, puppet-in-array): New helper functions. (puppet-indent-line): Rewrite to handle three more situations: indent elements in an array, indent single-line blocks, and ignore previous comment content when indenting non-comment lines.

Suggested by: Micah Anderson
(He also provided the test data.)

Notes: Michah points out that this change may have introduced an
infinite loop (he can cause Emacs to hang now). Will investigate and
fix in a separate change.
