Update to 7.5:
7.5  Tue Jan 31 15:15:43 CET 2006
        - further improvements to the careful mode detection, and font width
          detection:
          - fully double-wide fonts will now be correctly treated,
          - overlap detection was improved.
          - detect totally broken fonts (usually synthesized by xft).
          - careful mode forced refresh sometimes clashed with blinking,
            causing unnecessary screen redraws.
        - better handling of XFT combining characters.
        - enable antialiasing for some replacement fonts, as they
          might get used for other encodings which really need it, later.
        - remove spacing=100 from all default fonts, as this creates totally
          weird spacing (5 times normal) with xft.
        - removed iso10646 fallback, as xorgs iso10646 encoded fonts are mostly
          broken.
        - removed gnu unifont fallback, all combining characters are broken.
        - replace named colours by xorg's rgb.txt equivalents, to
          reduce round trip time on startup, and short-cut allocation
          of rgb:rr/gg/bb for xft.
        - short-cut allocation of rgb values in the xlib case
          (patch by Paco-Paco).
        - overhauled color management: smaller codesize, alpha support.
        - support "rgba:rrrr/gggg/bbbb/aaaa" color specifications and
          an "[alpha]" prefix.
        - try to work around Xft and Xrender forcing everything to be 100%
          transparent. Long Live Xft!
        - do not include X11/Intrinsic.h anymore, directly use
          Xlib/Xutil/Xresource directly.
        - try to find a nearest matching color when color allocation fails
          on a pseudocolor screen.
	- SYNCCVS: compared to rxvt-cvs 2006-01-28, no relevant changes.
        - fix version report (DA) (which was unfortunately broken).
        - changed version number report again, now to emulate xterm closer.
        - added the OSC sequence 702 to detect the urxvt version number.
        - small configure updates.
        - further RTT optimisations.

7.4  Sat Jan 28 15:26:27 CET 2006
	- screen background wasn't always erased properly when scrolling,
        - re-enabled clearing optimisation disabled in 7.4pre.
        - small configure updates for libptytty.
        - fixed version options: line output.
	- removed stoopid debugging message left in the code.

7.3  Wed Jan 25 22:47:35 CET 2006
        - don't let iso14755 or mouse reporting get into the way of perl
          (could lead to global grabs never being cleared).
        - experimental OnTheSpot editing support (-pe xim-onthespot).
        - moved Shift-Button2 paste combination to Meta-Button2.
        - the cutchars resource will now be respected and used by the
          selection extension.
        - added the "remote-clipboard" extension which just runs external
          commands to fetch and store the selection data.
        - added -depth switch that tries to get a different visual depth
          than the default (replaces the old PREFER_24_BIT logic).
        - removed (unused) arabic presentation form composing sequences.
        - be more strict when deciding that a core font glyph is too wide and
          needs the careful rendering mode.
        - allow more leeway for italic fonts when deciding that a character is
          too wide and needs careful mode.
        - redraw even more characters around characters using careful mode.
        - made selection-pastebin fully asynchronous.
        - reduced number of server turnarounds at startup by allocating
          atoms only once per display.
        - renamed on_keyboard_command to on_user_command.
        - changed version sos (ESC [ > c) response to be more compatible with
          xterm.
