Re: Virtually prefix headlines according to content

[indieterminacy]

Hi Rodrigo,

regarding syntax, it would be cool if you aligned the style to match Emacs' 
Hyperboles GitHub style:
=> https://github.com/rswgnu/hyperbole/blob/master/DEMO

```
** Github (Remote) References

For software developers who use Github for publishing and version control,
Github links are similar to social media links but reference specific Github
web pages.

Press the Action Key on github@rswgnu to go to RSW's gihub home page.
gh@rswgnu works too. 

References to project home pages look like this (the / is required):

  github#/hyperbole           (uses user default setting)
  github#/rswgnu/hyperbole

References to specific commits use the # hash symbol and short versions
of the git commit hash code:

  gh#rswgnu/hyperbole/5ae3550 (if include user, must include project)
  github#hyperbole/5ae3550    (project can be given with user default)
  gh#5ae3550                  (user and project defaults are used)

An Action Key press on the first commit reference above works because
user, project and commit hash code are all included.  The second and
third versions require the setup of default values, as explained in
the commentary near the top of "hib-social.el".

Similarly, the same file above explains how to link to pull requests,
issues, branches and tags.

```

FYI, Hyperbole has been making improvements with regards to utility with 
Orgmode.
It may be worth you looking into how that functionality is implemented.

Kind regards,


Jonathan McHugh
