[PATCH] kernel-doc: html mode struct highlights

[Randy Dunlap]

From: Randy Dunlap <[EMAIL PROTECTED]>

Johannes Berg reported that struct names are not highlighted
(bold, italic, etc.) in html kernel-doc output.  (Also not in
text-mode output, but I don't see that changing.)

This patch adds the following:
- highlight struct names in html output mode
- highlight environment var. names in html output mode
- indent struct fields in the original struct layout
