88deede54a tr: Fix '[=]=]' equivalence class. 
A closing bracket immediately after '[=' should not be treated as special.

Different from the submitted patch, a string ending with '[=' does not cause
access beyond the terminating '\0'.

03afb27c83 tr(1) attempts to convert \n[n][n] sequences into octal digits, but doesn't 
check to see that a given digit is actually an octal digit.  This leads to
unusual consequences if passed in values like \9.

ca99cfdd14 Add support for multibyte characters. The challenge here was to use 
data structures that scale better with large character sets, instead of
arrays indexed by character value:
- Sets of characters to delete/squeeze are stored in a new "cset" structure,
which is implemented as a splay tree of extents. This structure has the
ability to store character classes (ala wctype(3)), but this is not
currently fully utilized.
- Mappings between characters are stored in a new "cmap" structure, which
is also a splay tree.
- The parser no longer builds arrays containing all the characters in a
particular class; instead, next() determines them on-the-fly using
nextwctype(3).

21f53e9138 POSIX require complex processing of 'c-c' ranges: if one of the endpoints 
is octal sequence, range is taken in the byte values order, for non-octal
endpoints range is taken in the sorted collation order.

Implement it.

796263418b Special fix just for 
tr -[cC]s '[:upper:]' '[:lower:]'
case (or vice versa):
chars taken from s2 can be different this time
due to lack of complex upper/lower processing,
so fill string2 again to not miss some.

00611f0457 This patch address two problems. 
1st one is relatively minor: according our own manpage, upper and lower
classes must be sorted, but currently not.

2nd one is serious:
	tr '[:lower:]' '[:upper:]'
	(and vice versa) currently works only if upper and lower classes
	have exact the same number of elements. When it is not true, like for
	many ISO8859-x locales which have bigger amount of lowercase letters,
	tr may do nasty things.

	See this page
	http://www.opengroup.org/onlinepubs/007908799/xcu/tr.html
	for detailed description of desired tr behaviour in such cases.
