The 'y' command to yank text should leave the cursor at the start
of the range. This mostly works correctly in BusyBox vi but not
for whole-line yanks with backward motion, e.g. '2yk' to yank two
lines backwards. In this case the cursor is left at the end of the
range.
Fix this by returning the actual range from find_range(). Cursor
positioning following whole-line deletion is inconsistent between
vim and traditional vi. For BusyBox vi chose the option that uses
least code without being exactly compatible with either.
Also, find_range() preserved the value of 'dot', the current cursor
position. Since this isn't used by either caller of find_range()
we can save a few bytes by not bothering.

This allows to fix a problem that we wait for renew replies
for up to half the lease (!!!) if they never come.
Make it so that lease of 60 seconds is not "rounded up" to 120 seconds -
set lower "sanity limit" to 30 seconds.
After 3 failed renew attempts, switch to rebind.
After this change, we can have more flexible choice of when to do
the first renew - does not need to be equal to lease / 2.

Commit 7a8ceb4eb (vi: changes to line addresses for colon commands)
was supposed to address the issue:
When the last address is empty it should refer to the current line.
This was intended to allow ranges of the form '1,' with an empty
last address. It should have been expressed as:
When the last address is empty *and the second last isn't* it
should refer to the current line.
Otherwise a command like ':w' only writes the current line resulting
in serious loss of data.

Track the current and alternate filenames. The placeholders '%'
and '#' can be used in arguments to colon commands to represent
the current and alternate filenames respectively. Backslash can
be used to allow literal '%' and '#' characters to be entered.
This feature is controlled by the configuration option
FEATURE_VI_COLON_EXPAND.

It was possible for get_input_line() to store its NUL terminator
one character beyond the end of its buffer.
Code shrink in colon():
- Certain colon commands can be matched exactly, as any shorter
string would be matched earlier, e.g. ':wq' versus ':write'.
- Command matching is now case sensitive so there's no need to
check for 'N' or 'Q' suffixes.
- Rewrite how commands and arguments are split.

Improvements to ':read':
- When a file is read into the current buffer the cursor should be
placed on the first line read.
- If invoked without supplying a filename the current filename should
be used. This is similar to how ':edit' works.
- The code for ':edit' included an explicit check that the current
filename was non-empty. Both vim and traditional vi accept non-empty
filenames, only issuing an error message when an attempt to use such
a name fails.
- Allow undo of a file read.

Suppose vi is started with the command 'vi -R', that is, in readonly
mode with no filename. Attempting to save the file with 'ZZ' or ':w'
results in the message:
'(null)' is read only
Skip the code which prints this if no filename was provided, thus
falling through to file_write() which gives the more helpful message
'No current filename'.

Make line addresses behave more like vi:
- Vi allows the user to enter an arbitrary number of addresses,
though only the last two are used. This simplifies get_address()
by reducing the amount of state that needs to be carried.
- When a command requires a single address the last one entered is
used.
- If addresses are separated by a ';' instead of a ',' the current
line is updated to the left address. This may be useful when a
search is used to specify a range, e.g. ':/first/;/last/d'.
- When the last address is empty it should refer to the current line.
