allout-infer-header-lead

allout-infer-header-lead is an alias for `allout-infer-header-lead-and-primary-bullet' in `allout.el'.

(allout-infer-header-lead)

Determine appropriate `allout-header-prefix' and `allout-primary-bullet'.

Works according to settings of:

`comment-start'
`allout-header-prefix' (default)
`allout-use-mode-specific-leader'
and `allout-mode-leaders'.

Apply this via (re)activation of `allout-mode', rather than
invoking it directly.
