We don't want internal functions in the mode specific extention modules becoming
shared code. To avoid this, mark the functions as private and publish only through
a structure marked clearly as for testing only.
If these functions are useful as shared code they can be moved to the editor module
or else where.
Review of devlogs to use internal functions to also:
* select next and prev word
* select to start en of doc
* delete to end of line
* Add Cursor to next line
* Show diagnostics
* Show references

:bc close current buffer
:bn next buffer
:bp previous buffer
:rl reload current buffer
:qa! abandon without saving any buffer
