This change fixes a segfault in grep -e when no argument
has been provided. Thanks to Sean Hinchee for reporting
this issue.
Fixes #186.

When plumbing an address like `3-`, Acme selects line 1,
and similarly `3+` selects line 5.
The same problem can be observed for character addresses (`#123+`)
but _not_ for ones like `+`, `.+` or `/foo/+`:
The problem only occurs when a number is followed by a direction (`-`/`+`).
Following along with the example `3-` through `address` (in addr.c):
We read `3` into `c` and match the `case` on line 239.
The `while` loop on line 242ff reads additional digits into `c`
and puts the first non-digit back by decrementing the index `q`.
Then we find the range for line 3 on line 251 and continue.
On the next iteration, we set `prevc` to the last `c`,
but since that part read ahead _into `c`_,
`c` is currently the _next_ character we will read, `-`,
and now `prevc` is too.
Then in the case block (line 210) the condition on line 211 holds
and Acme believes that it has read two `-` in sequence
and modifies the range to account for the “first” `-`.
The “second” `-` gets applied after the loop is done, on line 292.
So the general problem is:
While reading numbers, Acme reads the next character after the number into `c`.
It decrements the counter to ensure it will read it again on the next iteration,
but it still uses it to update `prevc`.
This change solves the problem by reading digits into `nc` instead.
This variable is used to similar effect in the block for directions (line 212)
and fills the role of “local `c` that we can safely use to read ahead” nicely.

For some fonts, using box-drawing characters in the representative
text for computing the line height results in it being uncomfortably
high. Replace them with accented capitals and tall lower-case letters
which lead to a more conservative increase in the line height.
Fixes #162.

Double the width returned by CTFontGetBoundingBox when drawing.
Add box drawing characters for determining the line height.
Call freememimage(1) for the character memimage.
Fixes #18.

TERM_PROGRAM is the customary way to identify which kind of terminal
emulator program one uses on macOS.
This change sets TERM_PROGRAM to termprog since both variables are used
for the same purpose.

read(3) sometimes errors with EINTR on macOS over slow connections.
9pfuse(1) now retries read(3) instead of sysfatal(3)ing.

rc on amd64 stores ulimit values as 32-bit int, but the limits on
OpenBSD amd64 can exceed 2^31, so "ulimit -a" shows some values as
negative. This is a problem when I want to increase my ulimit but
the hard ulimit values are printed as negative.

Before, executing Get in a file rewound the window offset and
selection to the start of the file.
After this CL, Get preserves the window offset and selection,
where preserve is defined as "the same line number and rune
offset within the line". So if the window started at line 10
before and the selection was line 13 chars 5-7, then that
will still be true after Get, provided the new content is large
enough.
This should help the common situation of plumbing a
compiler error, realizing the window is out of date,
clicking Get, and then losing the positioning from the
plumb operation.

This makes it possible to use the scroll wheel to simulate
button 1 and button 3 clicks in the scroll bar. It scrolls
in the same way with variable scroll sections. Further down,
more lines per scroll etc...

Since macOS 10.13, opening the /dev/ptyXX files
always return ENOENT.
Consequently, we changed getpts to use openpty to
open a pseudoterminal, like on Linux and OpenBSD.
Fixes #90.

Bad remote file systems can change mtime unexpectedly,
and then there is the problem that git rebase and similar
operations like to change the files and then change them back,
modifying the mtimes but not the content.
Avoid spurious Put errors on both of those by checking file
content.
(False positive "modified since last read" make the real ones
difficult to notice.)

After making the build on macOS silent on commit 310ae03,
the build was broken on macOS lesser than 10.12 (Sierra).
This commit conditionally checks the version the of the
SDK before using the defined values for silent build.
Fixes #66.

Rename following .cvsignore files to .gitkeep since they are
required by the build (directories must exist before build):
- bin/fossil/.gitkeep
- bin/fs/.gitkeep
- bin/venti/.gitkeep
