A subfont with n chars has n+1 Fontchars, so scalesubfont() needs to
scale all n+1 info entries.

troff: support \~ as an alias for \ (#567) 
In groff, Heirloom Doctools troff, and neatroff, the `\~` escape
sequence produces an adjustable (paddable) but unbreakable space.
mandoc, which does not perform adjustment or render to typesetters,
supports the escape sequence as a synonym for `\ `, the same as `\0`.

This extension is of long pedigree: groff has supported it for at least
30 years, Heirloom for 17, mandoc for 13, and neatroff for 6.

Do the same as mandoc to prevent mis-rendering of documents using this
escape sequence.  Heirloom Doctools troff, a descendant of Documenter's
Workbench troff, would be a good place to look for a compatible
implementation of the adjustable semantics for this sequence.

85bfd19a7b devdraw/x11: fix modifier key handling for some XkbOptions 
Certain XkbOptions in X11 would change keysyms for modifier keys
between the key press and key release.

For example, under the XkbOptions "grp:shifts_toggle", though shift
keys remain Shift_L/R when pressed, they become ISO_Group_Next/Prev
when released.

This behavior makes devdraw unable to detect the release event
correctly and as a result mouse button 1 click always interpreted
as button 3 event after a shift key is used.

d92ac2d1b4 libdraw: fix out-of-bounds access to local buffer in event.c:startrpc() 
The function `startrpc()` stack allocates a local buffer of size 100:

```c
static Muxrpc*
startrpc(int type)
{
	uchar buf[100];
	      ^^^^^^^^
	Wsysmsg w;

	w.type = type;
	convW2M(&w, buf, sizeof buf);
	return muxrpcstart(display->mux, buf);
}
```

The function `convW2M()` is called passing `buf`. That function accesses
`buf` out-of-bounds:

```c
uint
convW2M(Wsysmsg *m, uchar *p, uint n)
{
  ...
  case Tcursor2:
    PUT(p+6, m->cursor.offset.x);
    PUT(p+10, m->cursor.offset.y);
    memmove(p+14, m->cursor.clr, sizeof m->cursor.clr);
    memmove(p+46, m->cursor.set, sizeof m->cursor.set);
    PUT(p+78, m->cursor2.offset.x);
    PUT(p+82, m->cursor2.offset.y);
    memmove(p+86, m->cursor2.clr, sizeof m->cursor2.clr);
    memmove(p+214, m->cursor2.set, sizeof m->cursor2.set);
    p[342] = m->arrowcursor;
    ^^^^^^
```

To fix the issue the size of local variable `buf` is increased from 100
to 512 to avoid out-of-bounds array access.

2ca8ede24a fossil: fix EOF detection when reading 9P message 
When the 9P connection is closed, reads on the connection will keep
returning 0. So, fossil ends up looping forever, trying to read a 9P
message, consuming 100% CPU. The fix interprets 0 bytes read as EOF.

Reproduce by killing the 9pserve process serving the fossil service, or
by listening on tcp and using 9p(1).

bb4b8acc26 src/cmd/fontsrv: pad subfile names to support correct file length 
For fonts with subfiles that go beyond the xffff range, the font file size
calculation is incorrect, since lines beyond that range have additional
characters. This patch pads all of the ranges and subfont names with
leading zeros in order to keep them all lines the same length and fixes the
font file length calculation.
