The latest version is now 1.0.13: please wait until that appears in the ftp
directory before getting joe.

Version 1.0.13 includes fixes for these bugs:

- A long sequence of searches or a search & replace with a lot of
  replacements would cause the editor to exit and display an 'Out of memory'
  message.

- If you deleted characters on a long line on a terminal which has a delete
  character command, spaces would someimtes be shifted in place of some of
  the characters.

- If you hit SPACE BACKSPACE RETURN on an otherwise empty prompt line, the
  editor would hang.

- If you typeahead a bunch of returns as the editor is starting, they would
  be converted to ^Js by the tty, which is the kill-line function in joe.

- When a backup file is created, any existing file of the same name is first
  deleted.  This fixes a problem when joe is being used for ELM- other
  people's backup files in the /tmp directory would prevent you from saving
  your own file.  This is also useful when root edits a file in some user's
  account.  The user wouldn't then be able to save his file because joe
  couldn't write to root-owned backup file.

Also these improvements to the search & replace system were made:

The wildcard \* now will not cross line boundaries.  This ends up being more
useful.

\+ now tries to make the longest possible match, instead of the shortest. 
This is much more intuitive:

	\[A-Za-z_]\+\[A-Za-z0-9_]  is all that's needed to match C
                                   identifiers.  It used to be:

	\[A-Za-z_]\+[A-Za-z0-9_]\[^A-Za-z0-9_]

\* still makes the shortest possible match though.  \c (like \*- but don't
stop in balanced expressions) should be used in 99% of all cases you needed
\* to make a longed match.

A full set of backslash escape sequnces is now available for search:

	\a, \n, \r, \b, \t, \e, \f

	match ascii: BEL, LF, CR, BS, TAB, ESC, FF.

	\377		Octal
	\xFF		Hex

	Can be used to match a character with specific ASCII code given in
octal or hex.

The escape sequences can be used inside of \[...] as well.
