Sync with FreeBSD and change their -h (that printed hex) to -x because
we were already using -h.

7ca3fbbe70 Avoid messing up the display when too many letters are guessed at once. 
The field to put them in was made 26 characters wide... but includes
the string "Guessed: ". So if you get to 17 it wraps to the next line
and clreol()'s it. Instead, when reaching this point step on the
"Guessed:" string instead.

e8699354fb cgram(6): use standard cursor keys, use standard shuffle algorithm 
The previous shuffle algorithm asked for 100 random numbers, on average.
The new algorithm asks exactly for 26 random numbers.

Curses predefines numeric constants for keys, and there is no apparent
reason not to use these standard keys for cursor movement.

de11d87641 introduce some common variables for use in GCC warning disables: 
GCC_NO_FORMAT_TRUNCATION    -Wno-format-truncation (GCC 7/8)
GCC_NO_STRINGOP_TRUNCATION  -Wno-stringop-truncation (GCC 8)
GCC_NO_STRINGOP_OVERFLOW    -Wno-stringop-overflow (GCC 8)
GCC_NO_CAST_FUNCTION_TYPE   -Wno-cast-function-type (GCC 8)

use these to turn off warnings for most GCC-8 complaints.  many
of these are false positives, most of the real bugs are already
commited, or are yet to come.


we plan to introduce versions of (some?) of these that use the
"-Wno-error=" form, which still displays the warnings but does
not make it an error, and all of the above will be re-considered
as either being "fix me" (warning still displayed) or "warning
is wrong."

c8bf876ced expand the internal consistency checks in truedirec() to avoid 
fallthrough cases.  now if direction turns up wrong (it should
not, but this code can't tell that, and convert it to an enum
that would also fix this, is more effort than this is worth.
