Plugin spec page crashes documentation

[Laurent Cozic]

This page:

https://joplinapp.org/help/dev/spec/plugins

gives the following error:

Parse error on line 12:
...])		rm1--8-->call	end
---------------------^
Expecting 'AMP', 'ALPHA', 'COLON', 'DOWN', 'DEFAULT', 'NUM', 'COMMA', 'MINUS', 'BRKT', 'DOT', 'PUNCTUATION', 'UNICODE_TEXT', 'PLUS', 'EQUALS', 'MULT', 'UNDERSCORE', got 'CALLBACKNAME'

Looks like it may be due to the "call" word which may be a reserved keyword?
