Add showfilename set option

Pressing control-G all the time to understand 'what file is in what
window' might be tedious. Instead, offer a configurable option
(default off) to display the file name in the lower left corner.

OK millert@ otto@

Require that the argument to the window option be non-zero.
A zero-row window would not be usable (no room to edit) and the
code is full of assumptions that "sp->t_rows - 1" >= 0.
From Erik Ruotsalainen, fixes a bug reported by Paul de Weerd.

Add an expandtab option, similar to what vim supports.
If set, expands tabs to spaces in insert mode as well as when
shifting and indenting/outdenting. If quoted with ^V, a literal
tab is inserted. Adapted from NetBSD, but this implementation
more closely matches vim's behavior. OK dlg@

Also apply stricter pledge when secure mode is set via rc file or command.

rcsid[] and sccsid[] and copyright[] are essentially unmaintained (and
unmaintainable). these days, people use source. these id's do not provide
any benefit, and do hurt the small install media
(the 33,000 line diff is essentially mechanical)
ok with the idea millert, ok dms

Fixes the `optindx' might be used uninitialized in this function
warning, fixes a spacing nit in a macro, and cleans up a very bad
preprocessor abuse (``if LF_ISSET(OS_DEF)''!)

optindx turns out to be the index number of the gigantic option
list at the beginning of the file. All we need to do is set it
before every ``goto err''.

The first four are global options, which you can just set optindx
to the second argument of o_set().

The last one is in a loop that uses cnt as the index. Since that
is cnt's only use, I just removed cnt and used optindx instead.
optindx is always updated and we use one less variable.

Update to 1.79 and install as vi/ex/view.

nvi 1.78:
+ Fix bugs when both the leftright scrolling and number edit options
were on.
+ Fix bug where splitting in the middle of the screen could repaint
incorrectly.
+ Fix first-nul in input bug, where random garbage was inserted.
+ Correct search and mark-as-motion-command bug, it's a line mode
action if the search starts at or before the first non<blank>.
+ Fix bug autoindent bug, where ^D could shift too far in the line.
+ Fix core dump where ! command called from the .exrc file.
+ Add the -S command-line option, which initializes vi to have the
secure edit option preset.

nvi 1.76:
+ Fix bug where ^V didn't keep input mapping from happening.
