Fix definition of F28 key.

Shitf modifier adds 12 to the function number of the function keys,
while Control adds 24, so Control + F4 generates F28
Fix comments in config.def.h to match field names.
Replace alignment tabs with spaces.
Prevent resizing stdin

This fixes a bug that the parent tty gets resized whenever you launch
st through command line.

The problem was that ioctl was resizing cmdfd before it gets
initialized in ttynew. Since cmdfd is a global variable, its initial
value is 0, and consequently stdin was being resized.
Update arg.h from sbase

sbase did some interesting modifications to arg.h (basically it
was fixed an incorrect use of the _ namespace), and this commit
take this last version for st.
query pixel size from matched font

Sorry for another duplicated mail. I found the patch is malformed
significantly. I've been away from my laptop for a while, so I'm quite
unfamiliar with the settings on this system...
Fix truecolor escapes, when both bg and fg are set

for example
echo -e "\e[48;2;255;0;0m\e[38;2;0;0;255m test "
should render on red bg with blue fg

also now elinks works correctly when using 'truecolor' option
in preferences

Make w3mimgdisplay work with st

Before this patch draw() calls drawregion which calls xdraws and then
updates whole window in one call thus overdrawing anything drawn by
w3mimgdisplay. After moving XCopyArea to xdraws it only updates the
regions which are being updated by XftDraw* functions. It may do a few
more calls to XCopyArea with this patch.

Make CONTROL + DELETE delete a line

If CONTROL + INSERT inserts a line then it seems natural CONTROL + DELETE
removes a line.
Make Shift+Home equal to CLS in ascii mode
Remove duplicated code in strhandle

The error condition was duplicated in two different switches.
This new version centralized the error handling in only one place.
Remove non defined behaviour in selcopy

It is not defined when lateral effects of expressions are
calculated, so an expression as:

	--last >= gp && !(selected(last - gp, y)

is non portable.
Removing the w3img support.

The patch to add w3img support destroys our way to handle fps and so stop
wasting resources on fast scrolling. Due to w3img being a hack to display
images in an ugly way, is there no need to support this. Use some real way to
display images.
Merge remote-tracking branch 'origin/master'
Add xstrdup function

Since we are using xmalloc, xrealloc ..., then it is not logical
call directly to strdup.

Add MC sequence

This sequence control when the printer is enabled or disabled. This
sequence control the behaviour of the -o option.
Style matters.
Style cleanup.

Add some note about the main reason why st is still that big.
