To me "^C" means "Cancel", and when I can cancel a prompt with it,
it feels natural to me to also "cancel" the display of a help text,
or the display of the file list (the browser) with it.

Not to me -- you can't do anything in it, there is no cursor, the help
lines change entirely... 

Anyone who works on the command line knows that ^C breaks or aborts most
commands.  When not knowing what to do, my first temptation is to hit ^C.
(BTW, the ^X exit key for help is listed as the last one in the help lines
-- it would be clearer if it were the very first.)

(If it were up to me, I would even make also ^G an exit key for help --
it would then be like a toggle; it might be the first thing I would try
before hitting ^C.)

Well, the change has been accepted in the past:

    svn diff -r3427:3428

Amongst several other changes, there is the addition of the Cancel key,
for both help text and file browser.
