When using the regexp builder and trying to match only lower case
letters (and spaces), Emacs also includes upper case matches. See attached
image (the regexp builder syntax in the image is set to string, but it happens with other syntaxes too)

Also, I am unable to find in the manual any information about the option of setting different syntaxes in the regexp builder (also the option is not mentioned in the regexp-builder docstring). So I would additionally like to report this as a documentation bug. (I am reporting it here, because maybe I did not search clever enough, but anyway then it is really hard to find for me.
Let me know if you would like me to report this separately.)
