+interrupt()						*interrupt()*
+		Interrupt script execution.  It works more or less like the
+		user typing CTRL-C, most commands won't execute and control
+		returns to the user.  This is useful to abort execution

+		:function s:check_typoname(file)
+		:   if fnamemodify(a:file, ':t') == '['

+		:       call interrupt()
+		:   endif
+		:endfunction
+		:au BufWritePre * call s:check_typoname(expand('<amatch>'))
