A better way to handle this is to have a key
(Icicles uses `M-.') that pulls text from the
buffer into the minibuffer, appending it to
whatever input text might already be there.
This is much more general than just pulling
in a command name from an Info buffer.
But it also means that users should be given
some way to control over _which_ text from the
buffer should be inserted into the minibuffer.
There are several reasonable possibilities.
As food for thought, Icicles handles this as
described here:
https://www.emacswiki.org/emacs/Icicles_-_Inserting_Text_from_Cursor
Summary:
Repeated `M-.' can have two different behaviors.
You can choose (by an option) which one to use.
1. Repeating `M-.' cycles through alternative
bits of text from the buffer. Each time you
hit `M-.' consecutively it inserts a different
string of text (replacing the previously
inserted one).
You can configure (user option) which kinds
of text to grab. By default the kinds are:
. `non-nil-symbol-name-nearest-point'
. `word-nearest-point'
. `list-nearest-point-as-string'
. Same (nearest list), but 2 levels up.
. Same (nearest list), but 3 levels up.
. `ffap-guesser' (but first deactivate a
large active region)
. `thing-at-point-url-at-point'
2. Repeating `M-.' grabs another thing of the
chosen kind. By default it is the next
word (using `forward-word').
IOW, you can either (1) keep using `M-.' to
insert _additional_ text things of a kind you
choose with an option setting or (2) use `M-.'
to cycle to get one thing of a kind that you
choose on the fly.
[Note that for your example, either (1) or (2)
does what you request: `list-coding-system'
is added to the minibuffer. `forward-word'
and `non-nil-symbol-name-nearest-point' both
grab that text.]
Whether vanilla Emacs would allow flexibility
to this degree is not so important as at
least having Emacs have a key that grabs
_something_ from the buffer text and appends
it to minibuffer input. Choice #2 above is
pretty simple to realize - give users an
option to specify which kind of text thing
they want to insert.
Alternatively, Emacs itself could provide
some context-sensitive DWIM to determine the
kind of text thing to grab. (As one user,
I prefer to control that choice myself, but
I'm sure that some others would be OK with
Emacs choosing.)
