RE: [External] : Re: master f117b5df4d: Add new functions eol and bol

[Drew Adams <drew.adams@oracle.com>]

Not sure what these new functions are for.  Couldn't
find the start of the thread - couldn't find further
back than this start (?), which doesn't explain
anything about them:

   Bikeshed welcome about the names, though.

Anyway...

Checking names that currently exist (18.1, emacs -Q) -

prefix position-:

 position-bytes - returns a buffer position, but
                  in bytes, not chars

prefix pos-:

 pos-visible-in-window-group-p
 pos-visible-in-window-p

 Neither returns a buffer position.

prefix posn-:

 posn-actual-col-row
 posn-area
 posn-at-point
 posn-at-x-y
 posn-col-row
 posn-image
 posn-object
 posn-object-width-height
 posn-object-x-y
 posn-point
 posn-set-point
 posn-string
 posn-timestamp
 posn-window
 posn-x-y

 These are mainly about a buffer position.

(Tried getting substring matches for `-pos-', `posn',
and `-position-', but it seems Emacs's `substring'
completion style doesn't work, and just shows prefix
matches?  Perhaps there's a category override that
renders trying to find substring matches for `C-h f'
useless?)

Finagling a bit I found these too, which also refer
to buffer positions: 

 get-pos-property
 Some mouse functions
 Quite a few functions that end in `-position'
