157e401636 Stylistic fixes: push variable into a local context (this part is going
to be split out into a function soon). Also there is no need to write
back the colon that we have NUL-ed - the string is going to be freed
anyway.

26478079f7 Buffers are already NUL-terminated so there is no need to explicitely add

ed293d7304 Mostly stylistic nits in preparation for splitting up Var_Parse:
use a more consistent style with regard to *str and str[0];
simplify code by introducing a temporary variable;
shift a break around and add braces where appropriate.

302288aba2 Style nits:
Move some assignments nearer to where they actually used. Convert a loop
from a for() to a while() to make it clearer and add braces to the long
body of it. Split assignment from variable declaration.

fd449ffe29 Revamp several Makefile nits:
- .PATH: is spelled ``.PATH: ''
	- Don't forget to use DPADD so ``make checkdpadd'' is
	  not broken.
	- LDADD should not come with + as it's empty in the
	  first place

04def62430 Finish the import of nc(1) from OpenBSD. This includes:
- Bring IPsec support from the ports collection [1].
	- Bring -o ("once only") option from the ports
	  collection [2].
	- Adopt the Makefile framework into
	  usr.bin/nc/Makefile.
	- Add a knob to control whether to build nc(1),
	  NO_NETCAT.
	- Bump __FreeBSD_version so ports collection can
	  detect this change.

Original patchset are contributed to the ports collection by:
[1] nectar, [2] joerg.

Note: WARNS?=6 patchset spined off in this commit, in order not
to take too many files off the vendor branch.

76628ce773 Save last displayed file by having the "last" pointer global and save it
during we show the first file's tail.  Instead of:

	tarsier% tail -f 1 2
	==> 1 <==
	foo
	bar

	==> 2 <==
	bar
	foo

	==> 2 <==
	bar2
	foo2

Now with this change, we have:

	tarsier% tail -f 1 2
	==> 1 <==
	foo
	bar

	==> 2 <==
	bar
	foo
	bar2
	foo2

While I'm there, move a comment to where it should belong to.  Also,
const'ify the "last" static because we will never need to change the
contents it points to.

b8900c134b None of the users of Buf_Discard used it to get rid of only a part of
the buffer. So replace Buf_Discard by Buf_Clear which just gets rid
of the entire contents.

435916b011 Minor cleanup: make brk_string to return argc only if the pointer to it
was non-NULL. This let's us eliminated an otherwise unused variable.

shellneeded can never return -1 so there is no need to check for it and
hence no need for a variable to hold the returned value.
