hideshow often toggles the parent by mistake

[mcandre]

I like using hideshow to fold my code. This works well in several modes such as python-mode. But when I try to toggle JSON data in json-mode, I observe a problem.

Steps to reproduce

package.json:

{
  "name": "dotfiles",
  "repository": {
    "type": "git"
  }
}

Go to line 3, any column except 16/17 where the curly brace lives. When you attempt to toggle the repository value, hs-minor-mode toggles the parent instead.

$ emacs -Q package.json
M-x json-mode
M-x hs-minor-mode
M-g g 3
hs-toggle-hiding

Expected

{
  "name": "dotfiles",
  "repository": { ... }
}

Observed

{ ... }

System

$ find $HOME/.emacs.d/.cask -type d -name '*json-mode*'

Thanks for lodging this issue. I've often thought it would be useful to be able to fold json but haven't yet got around to looking into it :)

hs-toggle-hiding hides the parent in other modes including c-mode, emacs-lisp-mode, and python-mode.
