Avoid writing past the end of the status bar
When waddnstr is called with a string that would extend past the
end of the window, the string is truncated, the cursor remains at
the last column, and ERR is returned. If this error is ignored and
the loop continues, the next call to waddnstr overwrites the character
at this column, resulting in a slight visual artifact. When the
window is too small to fit the full status line, it is effectively
truncated by one space on the right, since the string shown for
each channel begins with a space.  Additionally, if the last window
is the current window, the space is shown with a colored background.

To fix this, when waddnstr returns ERR, exit the loop in styleAdd()
early return -1 to propogate this error down to the caller.
