Fix slow redisplay in term-mode

Browse Source 
* lisp/term.el (term-mode): Move the setting of
bidi-paragraph-direction from 'ansi-term' to here, since term-mode
is also affected.  Do not merge to master, since there the problem
is solved in bidi.c by changing the regexps that delimit a
paragraph.  (Bug#23801)
