command and badly needed in sh(1) for everybody who wants to modify
the system-wide limits from inside /etc/rc.
The options are similar to other system's implemantations of this
command, with the FreeBSD additions for -m (memoryuse) and -p (max
processes) that are not available on other systems.
sh -c [-aCefinuvx] command_string [ command_name [argument ...] ] 1
4.56.3 Options
-c Read commands from the command_string operand. Set the
value of special parameter 0 (see 3.5.2) from the value of
the command_name operand and the positional parameters
($1, $2, etc.) in sequence from the remaining argument
operands.

When comparing my recent parser change against the ash in 1.1.5.1, i
found that a couple of other problems in the same area has been fixed
there, but not in 2.2. Semicolons and EOF do also delimit words...
The && and || tokens do also terminate a command, not only the
newline.
While i was at it, disabled trace code by default, it served no good
purpose since it required the use of a debugger anyway to be turned
on. Instead, placed a hint in the Makefile on how to turn it on.
This makes the shell ~ 10 % faster and ~ 4 KB smaller. :)

There is a bug in sh: the built in command "fc -l" generates
a core dump (*NULL in not_fcnumber).
According to the sh manual page (fc -l [-nr] [first [last]]), fc -l
is a correct sequence (in that case, values are defaulted to -16 and -1)
but fails when first is not given.
MKINIT line that doesn't have a comment on it (we have at least two).
This mkinit program was written by someone who obviously doesn't believe
in defensive programming. :-( There's a LOT of work that needs to be done
on this thing. :-( :-( :-(
find it in /bin. This is something of a kludge, I know, but consider
my limited alternatives: I can't make this an execvp() without making
people scream that I introduced a failure point or slowed down pwd,
and I can't make it an optional macro since crunch doesn't let you pass
arbitrary command-line args to the build of one of its crunch-ees.
This is the simplest, if not the nicest looking, solution I could come up
with.
This should fix it (passed my test cases). Originally discovered with
perl's Configure (well, in FreeBSD, I don't know how the NetBSD folks
discovered it).

automagically. -lfoo has to be right to work, but ${LIBFO0} is too
easy to forget or misspell; nothing checks it and it should be
different for shared libraries.
