bug#28774: Master, emacs-26: Can't add text property to built-in function name. |

Hi
After commit :3db388b0bf the following stopped working:
(global-set-key
"\M-x"
(lambda ()
(interactive)
(call-interactively
(intern
(ido-completing-read
"M-x "
(all-completions "" obarray 'commandp))))))
This package no longer works too:
https://github.com/DarwinAwardWinner/ido-completing-read-plus
Example error message:
Error in post-command-hook (ido-exhibit): (error "Attempt to modify read-only
object" "rename-buffer")
On the surface it looks like if I try to complete function defined in C (i.e,
built-in),
I get this error because the symbol/name is read only.
Call chain like this :
ido-completions
put-text-property
add_text_properties_1
validate_inerval_range
create_root_interval
CHECK_IMPURE
pure_write_error
I still reproduce it on
emacs-26 - 5d51403ceb
master - 6abff55b55
Temporary fixed with ido-name override:
(defun ido-name (item)
;; Return file name for current item, whether in a normal list
;; or a merged work directory list.
(concat (if (consp item) (car item) item)))
Thanks,
Ilya
