I missed to tell that I'm talking about terminfo on Linux and now that
I compare terminfo entries on different Linux distros, I see that they
disagree about the rxvt settings:

Red Hat Enterprise Linux 4:
$ rpm -qf /usr/share/terminfo/r/rxvt-basic 
$ infocmp -I rxvt-basic | grep 'cu[bfu]1'
        cub1=^H, cnorm=\E[?25h, cuf1=\E[C, cuu1=\E[A, dch1=\E[P, 
        kcub1=\E[D, kmous=\E[M, knp=\E[6~, kpp=\E[5~, kcuf1=\E[C, 

OpenSuSE 10.2:
$ rpm -qf /usr/share/terminfo/r/rxvt-basic 
$ infocmp -I rxvt-basic | grep 'cu[bfu]1'
        cub1=^H, cnorm=\E[?25h, cuf1=\E[C, cuu1=\E[A, 
        kich1=\E[2~, kcub1=\EOD, kmous=\E[M, knp=\E[6~, kpp=\E[5~, 
        kcuf1=\EOC, kDC=\E[3$, kslt=\E[4~, kEND=\E[8$, kHOM=\E[7$, 
        kLFT=\E[d, kNXT=\E[6$, kPRV=\E[5$, kRIT=\E[c, kcuu1=\EOA,

Same picture here:

Red Hat Enterprise Linux 4:
$ rpm -qf /etc/termcap
The termcap entry for rxvt-basic has
	 kd=\E[B  ku=\E[A  kl=\E[D  kr=\E[C

OpenSuSE 10.2:
$ rpm -qf /etc/termcap
The termcap entry for rxvt-basic has
	 kd=\EOB  ku=\EOA  kl=\EOD  kr=\EOC

Unfortunately I was playing with the OpenSuSE installation while
debugging rxvt, and I only tested Cygwin's rxvt against the SuSE box.
Apparently the termcap/terminfo entries (same as above for the other
rxvt entries) are broken on SuSE.  Weird.  That should be a lesson to
me, I guess...

Yes, I agree.

It doesn't have to do with line art.  If cursor and home/end keys don't
work, you have, for instance, problems moving in mutt's menus.

I was working under the premise that different Linux distros wouldn't
differ in such essential details.  Oh well...
