[ESS] ?foo doesn't work in development [sometimes]

[Richard M. Heiberger]

Quotes in help are inconsistent.

I am using ESS 13.09

Macintosh with
GNU Emacs 23.4.1 (x86_64-apple-darwin, NS apple-appkit-1038.36) of
2012-01-29 on bob.porkrind.org
?[ work
?? works
??? freezes, I need C-g C-c C-c to break out.
?'[' says No documentation for ''['' in specified packages and libraries:
?"[" says Error: unexpected ')' in ".ess_help(""["", help_type="text")"
?`[` says No documentation for '`[`' in specified packages and libraries:
?'?' says No documentation for ''?'' in specified packages and libraries:
?"?" says No documentation for
'/Library/Frameworks/R.framework/Resources/library/base/help/Arithmetic'
in specified packages and libraries:

The above differ from what I was seein in 13.05-1


Windows with
GNU Emacs 24.2.91.1 (i386-mingw-nt6.1.7601) of 2012-12-27 on MS-W7-DANI
seems to be the same as Mac, I didn't test all of the above.
