MacVim snapshot 159 vim spell randomly flagging first word in lines

[trondbn]

Describe the bug
MacVim snapshot 159 vim spell randomly marks a lot of words that appear first in their line as bad. First suggested correction seems to always be capitalizing the word, but after accepting this it is still marked as bad.

To Reproduce
Detailed steps to reproduce the behavior:

1. Run mvim --clean
2. Edit a text file, such as the one attached to this report.
3. Type ':set spell'
4. Red squiggly lines:
   

Expected behavior
Less squiggling: (taken with snapshot 157)

Environment:

• Vim version: 8.1.2168
• OS: macOS 10.15 Catalina (19A602)
• Terminal: GUI

Additional context
Cleaning out ~/.vim/spell/ does not help

Sample file

I think this is vim/vim#5072 which was fixed in vim/vim@7751d1d (v8.1.2172). There should be an update soon to address app notarization issues which will come with this.

We had a recent discussion about this at vi.stackexchange.com

Copying here my answer from there:

This is a known bug, introduced by patch v8.1.2153 that has since been fixed with patch v8.1.2172, so you'd need to update your MacVim to a new Version.
