xterm-280-1 breaks the Home and End keys of my Lenovo X220: those keys still work fine in other applications (such as xev), but xterm apparently grabs them and never forwards the event to the underling application (shell, vim, mutt, etc.).

This is introduced by the change "add modifyKeyboard resource to support keypad-modifier changes per request by Thomas Wolff add XK_Home / XK_End to editing-keypad checks". Applying the attached patch (which reverts part of this change) fixes this issue. I am not sure however if this is the right way this should be done...
This task depends upon

I confirm, after upgrade, both "Home" and "End" keys are broken in xterm (also with a Lenovo x220).

I tried instructions in the wiki, but doesn't help ...

Michaël: If the wiki does not help, why mention it at all? Especially when I already diagnosed the problem and came up with a patch...

I also have this problem with xterm-280-1, using a 'Chicony Electronics Co., Ltd Genius LuxeMate i200' keyboard (according to lsusb) with the 'us' keyboard map.

Setting the xterm to use vt220 keyboard seems to work on the command line and in vim, etc. To make it the default, I placed the following line in my ~/.Xdefaults file:
XTerm*sunKeyboard: true

To try this out before making it the default, start xterm, ctrl+left click in the window, select 'VT220 Keyboard' and try out your home/end keys.

"sunKeyboard" breaks MC.
"VT220 Keyboard" is not work in "man" and "less" commands.
"XTerm*tcapFunctionKeys: true" seems to be working.

What is upstream saying about this?

The Upstream (Thomas E. Dickey) say:
"yes... someone reported this a few hours ago, and I'll be uploading #281 shortly.
