Clarify comment in example key-handler (#89)
currently, the key-handler will not receive the `S-` modifier if there's
a capital equivalent of that KEY.
if https://github.com/nsxiv/nsxiv/pull/78 is to be merged, then this
behaviour may change.

however as it currently stands, we should fix the comment. we can update
it later if needed.

# Example for $XDG_CONFIG_HOME/nsxiv/exec/key-handler
# Called by nsxiv(1) after the external prefix key (C-x by default) is pressed.
# The next key combo is passed as its first argument. Passed via stdin are the
# images to act upon, one path per line: all marked images, if in thumbnail
# mode and at least one image has been marked, otherwise the current image.
# nsxiv(1) blocks until this script terminates. It then checks which images
# have been modified and reloads them.
# The key combo argument has the following form: "[C-][M-][S-]KEY",
# where C/M/S indicate Ctrl/Meta(Alt)/Shift modifier states and KEY is the X
# keysym as listed in /usr/include/X11/keysymdef.h without the "XK_" prefix.
# If KEY has an uppercase equivalent, S-KEY is resolved into it. For instance,
# K replaces S-k and Scedilla replaces S-scedilla, but S-Delete is sent as-is.
