feature/tree-sitter 784f53a215 11/14: ; Replace error with signal in treesit.el

[Yuan Fu]

branch: feature/tree-sitter
commit 784f53a2152181b687f9543ddba9c393dda1c715
Author: Yuan Fu <casouri@gmail.com>
Commit: Yuan Fu <casouri@gmail.com>

    ; Replace error with signal in treesit.el
    
    (or (treesit-parser-create language)
        (error "Cannot find a parser for %s" language))
    
    is turned into
    
    (treesit-parser-create language)
    
    because treesit-parser-create never returns nil.  (We used to use
    treesit-get-parser which don't create parser automatically.)
    
    * lisp/treesit.el (treesit-buffer-root-node): Replace error with signal.
