fix tty problem et al
internals/internals.texi: Add section on correctly merging a branch back into the trunk.
console-tty.c, eval.c, event-unixoid.c, file-coding.c, file-coding.h, lisp.h, print.c, sysdep.c: Fix data corruption error in print.c from print_depth becoming
negative. Borrow primitives internal_bind_int,
internal_bind_lisp_object from my stderr-proc ws, soon to be
integrated; use them to properly bind print_depth et al.
First fix for TTY problem. The basic problem is I switched things
so that the TTY I/O is filtered through a coding system, for the
support of kterm and such, that speak JIS or similar
encodings. (#### I ***swear*** I had this working way back in
19.12.) Anyway, this introduced buffering issues, in which instead
of one char being read, it tried to read 1024 chars. I tried
setting the stdin descriptor non-blocking, but it doesn't appear
to work on Cygwin. (#### Andy, do you know anything about this?)
So I fixed it elsewhere. If you get weirdness on the TTY, look in
console-tty.c and see how it gets the coding system; maybe there's
a way to change it (and if not, there should be!).
Also fix warning in sysdep.c.
