This patch unifies look of eend used in bash & python code, additionally fixing
 few inconsistences in bash code. What I've changed is:
 1. Removed additional (useless?) space in RC_ENDCOL eend which were overwriting
    last char of RC_DOT_PATTERN (and adjusted ENDCOL width respectively).
 2. Fixed the COLS declaration in unset_colors() to not include screen height
    as it is set and used that way everywhere else.
 3. Moved the 'global' COLS decrease directly into ENDCOL declaration as it was
    probably useful only for that and broke both non-RC_ENDCOL eend and
    RC_DOT_PATTERN.
 4. Make the COLS-- unconditional as it is useful for curses too (and that
    couldn't be determined through ${TERM}), it looks better and it certainly
    won't hurt on other consoles.
 5. Adjusted the Python output width to match (visually) the bash one. Not sure
    about the source of that inconsistence though. I'll investigate that
    further in a while.
