sh: Some changes to stderr flushing:
* increase buffer size from 100 to 256 bytes
* remove implied flush from out2str(), in particular this avoids unnecessary
flushing in the middle of a -x tracing line
* rename dprintf() to out2fmt_flush(), make it flush out2 and use this
function in various places where flushing is desired after an error
message

sh: Improve handling of setjmp/longjmp volatile:
- remove ineffective and unnecessary (void) &var; [1]
- remove some unnecessary volatile keywords
- add a necessary volatile keyword
- save the old handler before doing something that could use the saved

Fix the eval command in combination with set -e. Before this change the shell
would always terminate if eval returned with a non-zero exit status regardless
if the status was actually tested. Unfortunately a new file-scope variable
is needed, the alternative would only be to add a new parameter to all
built-ins.

Add a `bind' builtin command, which is simply a wrapper around libedit's
builtin command of the same name. This allows the key bindings for the
shell's line editor to be changed.

Fix typo causing ``fc -e'' to not work correctly. getopt() sets optarg,
not shoptarg.

Adding an entry to the history with H_ENTER moves libedit's internal
history cursor. Reset the cursor after adding the entry to the history
when doing ``fc -s'' so the output is correct.

Add rcsid. Spelling.

When NO_HISTORY is defined and the history command is used
show an error message.

compare return value from getopt against -1 rather than EOF, per the final
posix standard on the topic.
