I thought the same than you.  I just discovered in this bug that square
parens also matters:
Compare I), II) w/o and w/ escaped '[':
I) It confuses `beginning-of-defun':
emacs -Q thingatpt.el
M-g g 229 RET
C-M-a ; go to line 222 instead of line 220.

II) It confuses `indent-for-tab-command':
emacs -Q thingatpt.el
M-g g 220 RET
C-SPC C-M-e TAB ; indentation doesn't change and it looks wrong.
