`move-beginning-of-line` move to wrong position on heading when markdown-hide-markup is enabled #815

Open kuranari opened 7 months ago

kuranari commented 7 months ago

When markdown-hide-markup is enabled, invoking move-beginning-of-line （C-a） on a header line incorrectly moves the cursor to the previous line.

Headings do not use the invisible property. However, this appears to be an intentional choice. https://github.com/jrblevin/markdown-mode/issues/130#issuecomment-307441856

Expected Behavior

Move to beginning of current line

Actual Behavior

Move to previouse line

Steps to Reproduce

Place the following in /tmp/emacs/.emacs:
```
(setq custom-file "/dev/null")
```

(package-initialize) (add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/")) (package-install 'markdown-mode)

(setq markdown-hide-markup t)


2. Make `sample.md`
```md
text

# Heading

HOME=/tmp/emacs emacs -Q --load /tmp/emacs/.emacs /tmp/emacs/sample.md
Move to line 3
Hit C-a (move-beginning-of-line）

📝 Research Findings

When evaluating the following, it no longer moves to the previous line (not a fundamental solution).
