bug#49544: 26.3; shift arrow command runaway

[Kunz, Chris]

Emacs is running under WSL (Ubuntu).  It doesn't happen in any application 
under Windows 10 (including GNU Emacs 25.2.1 compiled for Windows).  It also 
doesn't happen in the xterm window running under WSL.  It could be WSL or 
VcXsrv.  I will try to move to WSL 2 and see if that solves the issue.

Thanks,
Chris

Is this some "accessibility" feature of your system, perhaps?  There's no such 
feature in Emacs, AFAIK.
