It turns out that POSIX specifies more should prompt with the file name,
not --More-- like the old UCB more did.  Back out a hack I did to
make the prompt look like the old UCB more.
Call fsync() _after_ tcsetattr() and pass tcsetattr the TCSASOFT
flag. Seems to help the occasional problem with messed up terminal
input after suspending less.

Repair interrupted reads; fixes ^Z. OK deraadt@
return the old behaviour for "more":
if you press F ^C, you would be left at a prompt at the end of the file.

ok nicm@
Don't create a history file called -... doh. Pointed out by jmc.
Reverse the default of the -c flag from off to on to prevent the text
being displayed in the wrong place initially and then jumping when first
redrawn (such as when searching).

Quit if write(2) returns -1 when writing to the tty, which can
happen if the tty is revoked.  OK deraadt@
fix a leak in an error path
ok krw@ deraadt@
In "more" mode, POSIX says the command specified by the -p option
should apply to every edited file, not just the first one.  It is
equivalent to less's ++ option.  Patch sent to upstream.  OK shadchin@
Unlike less, more should use basic regular expressions.
OK schwarze@
Use volatile sig_atomic_t, not int, for the sigs variable. Also
move the call to bell() out of u_interrupt() (a signal handler).
OK and with help from deraadt@
