As reported in bug 11796 BusyBox vi incorrectly handles changes
to a word at the end of a line. If the following line starts
with whitespace changing or deleting the last word of a line
with the 'cw' or 'dw' commands causes the lines to be joined.
This happens because the range for the change returned by
find_range() covers all whitespace after the word, including
newlines. The problem can be fixed by setting 'ml' to zero
to indicate to yank_delete() that processing should stop at
the end of the current line.
However, this results in a new problem. 'dw' correctly deletes
all whitespace following the word but so does 'cw', which should
preserve the trailing whitespace. To fix this the code to omit
whitespace from the change is modified to include all whitespace
not just blanks.

Setting PS1 to:
PS1='`xxx(`'
causes the shell to terminate with the error:
sh: syntax error: unexpected end of file (expecting ")")
This happens because old-style backquotes require the input to be reread
and thus call setinputstring() a second time. Prevent the problem by
unwinding all recently opened files in expandstr().

The proxying is documented as follows:
P:/url:[http://]hostname[:port]/new/path
Howeverm urlcopy is not a true copy anymore when it is fdprint'ed
to proxy_fd, this is because percent_decode_in_place() is called
after the copy is created.
This breaks reverse proxying all URIs containing percent
encoded spaces, e.g. - because a decoded URI will be printed out
to proxy_fd instead of the original.
The fix keeps the logic in place to canonicalize the uri first,
before reverse proxying (one could argue that the uri
should be proxied completely unaltered, except for the prefix
rewrite).

after the boot, and appearing _downed_. ifplugd then fails to detect
"link up". Thus, depending on how service startup
("ip link set dev eth0 up") races with driver initialization,
ethernet randomly fails to initialize on boot.
