included twice by lprint.c, which included both finger.h and extern.h.
finger.h, in turn, includes extern.h. The redundant include of extern.h
was removed from lprint.c, as part of this change, but the include guards
were added anyway out of spite.
Fixed a nearby bug. The "play it safe" code in dosysctl() was unsafe
because it overran the buffer by 1 if sysctl() filled all of the buffer.
Fixed a nearby style bug in output. Not just 1, but 2 extra newlines
were printed at the end by "vmstat -m" and "vmstat -z". Don't print
any newlines explicitly. This depends on 2 of the many formatting
bugs in the corresponding sysctls. First, the sysctls return an extra
newline at the end of the strings. This also messes up output from
sysctl(8). Second, the sysctls return an extra newline at the beginning
of the strings. This is good for separating the 2 tables output by
"vmstat -mz" and for starting the header on a new line in plain sysctl
output, but gives a bogus extra newline at the beginning for "vm -[m | z]"
and "sysctl -n [kern.malloc | vm.zone]".
Fixed some nearby style bugs in the source code:
- the same line that misspelled 0 as NULL also spelled NULL as 0.
- the size was doubled twice in the realloc loop.
- the "play it safe" comment was misleading. Terminating the buffer
is bogus because dosysctl() is only meant to work with sysctls that
return strings and the terminator is part of a string. However, the
kern.malloc sysctl has more than style bugs. It also doesn't return
a string. Termination is needed to work around this bug.
the .for loop:
- Replaced four global variables in parse.c with one.
- Made Parse_FromString() accept the "lineno" as an argument.
- Fixed line numbering when there are escaped newlines in the
body of the .for loop.

1) Constness, unusedness and size_tness.
2) Don't clobber the value returned by hid_report_size in the daemon case.
3) Don't misspell "sizeof buf" as 100.
4) Don't run off the end of a buffer if the pid is about a google.
5) Avoid shadowing the usage function.

This bug has been around for 22 months... either nobody uses printf
with floating-point values, or people are forgetting to check their
return codes.

Use %ju and an (uintmax_t) cast to print size_t values.
Use %jd and an (intmax_t) cast to print off_t values.
Use off_t variables to hold the difference between two off_t values.
Don't bother with unsigned char where char will do nicely.
