Re: Font-lock error when using "flyspell-buffer" upon opening a tex file

[Ruiyang Wu]

To get rid of the errors, I have to defer running “flyspell-buffer” as late as 
possible. For example, using idle timer with 0s idle interval for 
“flyspell-buffer” will work. However, idle timer is a bit tricky to use and 
will cause warnings in other modes (e.g. markdown mode). So this workaround is 
still not ideal. I wonder what would be the proper fix for this issue. Thank 
you for the help!

Best,
Ruiyang
