bug#32959: 26; Emacs manual index entry `C-SPC C-SPC disabling Transient Mark'

In that case, the plain `C-SPC C-SPC' should be something like
`C-SPC C-SPC, set mark without activating'.

That's certainly better than "disabling". Thx.

Do you know of other places in Emacs where we speak of
activating/deactivating a _mode_? Actually, yes, it turns
out there are a few - but very few. Should you change
your mind and decide to correct them, here they are:

In the Emacs manual:

Node `CUA Bindings':
"CUA mode by default activates Delete-Selection mode..."

Node `Indentation Commands':
"the command activates a transient mode..."

Node `Key Bindings':
"activating a mode might override your..."

In the Elisp manual:

Node `Minor Modes':
"possible to activate and deactivate minor modes..."

That's it, for the manuals - 4 occurrences altogether.

In doc strings, we also have a few occurrences:

vc-mode: "This minor mode is automatically activated..."
allout-mode: "automatic activation of `allout-mode'"
allout-auto-activation: "outline mode auto-activation"
Info-edit-mode-hook: `Info-edit-mode' is activated
indent-rigidly: "any other key deactivates the transient mode"
set-mark-command: "activates `transient-mark-mode'"
follow-delete-other-windows-and-split: "Follow mode is activated"
ps-prologue-file: "major/minor-mode is activated"
isearch-yank-word-or-char: "`subword-mode' is activated"
vc-refresh-state: "VC mode is deactivated"

That's very few occurrences, for all of Emacs: 4 in manuals, 10 in doc strings.

I would say "turn on" or "enable" a mode, which is what
Emacs says everywhere else, AFAIK. These occurrences
are just typos/slips, I imagine.
