If a line begins with a word that matches one of the languages listed in `g:markdown_fenced_languages`, the line is wrongly detected as being the start of a fenced code block for that language. This commit ensures that a line is only treated as the start of fenced code block if the line begins with three or more consecutive backtick or tilde characters (with optional leading space characters).
