tab filename insertion in Windows

[Tait <gnu...@t4...>]

Something new as of gp 4.6.0 on Windows is that a tab character, entered
into the interactive terminal, expands into a filename. Can this behavior
be disabled via some configuration?

I often develop files with \-continuations, e.g.
plot '-' title "nzrgrdr" \
	'-' title "ghlallaghp" \
	'-' title "xyzpthrtk"

Note the tab-indent on the line continuations. When I 'load' such a file
into gnuplot, it works fine, but often in the course of development or
helping others, I copy-and-paste these into the interactive terminal.
This worked before, but now breaks because the leading tab expands to a
filename, which is of course a syntax error.

Vim works around issues like this by using paste detection, but the
easier solution is probably just to disable filename-expansion. The
current situation makes it impossible to interactively type anything
containing a tab. For example, print "x    y       result" even fails
because the tab cannot be inserted without turning into a filename. The
usual character-escape or ctrl-v quote-literal terminal tricks that would
work on *nix do not work on the Windows terminal.
