 o	Automatically insert the current comment leader after hitting 'o' or

 q	Allow formatting of comments with "gq".

+							*fo-v*
 v	Vi-compatible auto-wrapping in insert mode: Only break a line at a
 	blank that you have entered during the current insert command.  (Note:
 	this is not 100% Vi compatible.  Vi has some "unexpected features" or
 	bugs in this area.  It uses the screen column instead of the line
 	column.)
+							*fo-b*
 b	Like 'v', but only auto-wrap if you enter a blank at or before
 	the wrap margin.  If the line was longer than 'textwidth' when you
 	started the insert, or you do not enter a blank in the insert before
 	reaching 'textwidth', Vim does not perform auto-wrapping.
+							*fo-l*
 l	Long lines are not broken in insert mode: When a line was longer than
 	'textwidth' when the insert command started, Vim does not
 	automatically format it.
+							*fo-m*
 m	Also break at a multibyte character above 255.  This is useful for
 	Asian text where every character is a word on its own.
+							*fo-M*
 M	When joining lines, don't insert a space before or after a multibyte
 	character.  Overrules the 'B' flag.

 B	When joining lines, don't insert a space between two multibyte
 	characters.  Overruled by the 'M' flag.
+							*fo-1*
 1	Don't break a line after a one-letter word.  It's broken before it
 	instead (if possible).

 ]	Respect textwidth rigorously. With this flag set, no line can be
 	longer than textwidth, unless line-break-prohibition rules make this
 	impossible.  Mainly for CJK scripts and works only if 'encoding' is
 	"utf-8".
+							*fo-j*
 j	Where it makes sense, remove a comment leader when joining lines.  For
 	example, joining:
 		int i;   // the index ~
 		         // in the list ~
 	Becomes:
 		int i;   // the index in the list ~
+							*fo-p*
 p	Don't break lines at single spaces that follow periods.  This is

 	sentences separated by two spaces.  For example, with 'textwidth' set

+Legacy Vim script has some tricks to make a for loop over a list handle
+deleting items at the current or previous item.  In Vim9 script it just uses
+the index, if items are deleted then items in the list will be skipped.
+Example legacy script: >
+	let l = [1, 2, 3, 4]
+	for i in l
+	   echo i
+	   call remove(l, index(l, i))
+	endfor
+Would echo:
+	1
+	2
+	3
+	4
+In compiled Vim9 script you get:
+	1
+	3
+Generally, you should not change the list that is iterated over.  Make a copy
+first if needed.

+To built Vim on Ubuntu from scratch on a clean system using git:
+	Install tools required to be able to get and build Vim:
+	% sudo apt install git
+	% sudo apt install make
+	% sudo apt install clang
+	
+	Build Vim with default features:
+	% git clone https://github.com/vim/vim.git

+	% make
+
+	Run tests to check there are no problems:
+	% make test
+
+	Install Vim in /usr/local:
+	% sudo make install
+
+	Add X windows clipboard support (also needed for GUI):
+	% sudo apt install libxt-dev
+	% make reconfig
+
+	Add GUI support (ignore compiler warnings):
+	% sudo apt install libgtk2.0-dev
+	% make reconfig

 before starting configure.  Example:
 
-	env  CFLAGS=-I/usr/local/include  LIBS=-lm  make

 for or figures out by itself.  First try running configure without extra
