suggestion: enable SIGNALS_VIA_CHARACTERS in s/gnu-linux.h

[Eric Hanchrow]

For a long time I'd been annoyed that I couldn't use C-c C-c to
interrupt processes that I'd started via "sudo" in shell-mode.  For
example, I'd type

        M-x shell RET

then

        sudo find / 

then as it spewed tons of lines into the shell buffer, I'd frantically
type C-c C-c, to no avail.  This was only a problem on GNU/Linux,
however; on FreeBSD, for example, C-c C-c works nicely.

Anyway, someone suggested that I try enabling (i.e., uncommenting)
SIGNALS_VIA_CHARACTERS in s/gnu-linux.h.  I did that, and it worked
fine -- and in fact has been working fine for months, on both a 2.4
and a 2.6 kernel.

I wonder, then, if it's time to reactivate that.  The comment which
says it doesn't work appears to be thirteen years old; presumably the
Linux kernel has changed since then ;-)
