sp-get-buffer-char-syntax: Symbol’s function definition is void: syntax-class-to-char

[rechvs]

Expected behavior

Calling sp-backward-kill-word kills the word before point.

Actual behavior

The function displays the following error in the minibuffer:

sp-get-buffer-char-syntax: Symbol’s function definition is void: syntax-class-to-char

Steps to reproduce the problem

In any file with Smartparens mode active, call sp-backward-kill-word.

Hmm, seems like the function syntax-class-to-char was introduced in Emacs 28. I'll add a compat function for it.

@Fuco1 I’m afraid the problem still persists. Should I open a new issue?
