search-forward-regexp fails to search uppercase classes of characters in regexp.

How to reproduce:

1) emacs -q --no-site-file --no-splash
2) type the following in *scratch* buffer
     (search-forward-regexp "[A-Z]")  abCd
3) evaluate the first expression.

Expected: cursor after B
Results: cursor after a

Regards

I believe this is working as intended: see the node Searching and Case
in the Emacs Lisp manual.

This is (I believe) expected behaviour with case-fold-search set
to t, the default.

Perhaps the docstring of search-forward-regexp should mention
this variable, as is done for search-forward.

Cheers,
Lawrence
