Use explicit braces to avoid ambiguous else.

Prevent buffer overflow when forcibly terminating an escape character.

Obtained from: OpenBSD
Note: In the case of a full buffer the OpenBSD implementation will
leave in the format string an invalid escape sequence. This appears
to be harmless with our C library, but according to C99 this can
cause undefined behavior.

MFC after: 2 weeks

Correct handling of format strings with escaped % specifications.

Note: It would be nice to be able to implement getformat() using
fmtcheck(3), but fmtcheck does not distinguish between signed and
unsigned types, a facility jot needs to perform range checks on its
output.

Style facelift.
- Reduce the number of global variables
- Make global objects static
- Use bool consistently
- Sort getopt arguments and their processing
- Add function comments
- Change notlast != 0 into !last

Use a more sensible default of 1 or -1 when only the start and
end values are specified.

Do What I Mean when the user asks for random integers or characters.
Up to now jot would fail to generate the last character in the range
or skew the integer distribution in a way that would generate the numbers
in the range's limits with half the probability of the rest.

This modification fixes the program, rather than documenting the
strange behavior, as suggested in docs/54879.

Also, correctly specify the range of random(3).

Avoid negative array indices: an empty string can also be used
to specify a default value.

Restore jot's ability to use a seed for producing a deterministic
sequence of random numbers.
This functionality was lost in revision 1.9 when the random number
generator was switched to arc4random.

Avoid passing negative values to <ctype.h> functions on machines with
signed chars.

Fix jot so that 'jot -r -w %d 1 1 4' never prints 4. Previously, it
would print it with probability 1/2**32. It seems that the correct
behavior is to print 4 with probability 1/4, but I'd like to avoid
breaking POLA until all the range inconsistencies in jot can be fixed
in one pass. See PR for details.

Actually, arc4random() returns a uint32_t, not an int. Use the correct
constant, just in case uint32_t turns into a `short' ten years from now.
If this is MFC'd it will be necessary to hard-code the constant since
-stable doesn't have UINT32_MAX.

Replace the cast I removed in rev. 1.16 with a slightly less evil one

Silence warnings and compile with WARNS=2 on i386 and alpha.

Miscellaneous cleanups; sync to OpenBSD as much as feasible.
Noteworthy changes include:
* Use getopt(3).
* Fix overflows in -b and -w options.
* Use strlcpy(3) and snprintf(3) in favor of strcpy(3) and
sprintf(3), respectively. Also check return values of the former
two.
* Fix lots of other gratuitous differences with OpenBSD.

Don't call printf with no format string.

Back out rev 1.11, about which bde had concerns, and instead implement

the desired conversion format specifier.
