1.2
Added helper function __expand_tilde_by_ref() Expands only tilde (~), if first char, in variable. This function displays bash's capabilities of passing a variable by reference (variable indirection) which allows us to avoid using a subshell. As far as I can see it works surprisingly well?
(testsuite) FreeBSD and Solaris sed compatibility fixes.
(testsuite) Add test case for _filedir with directory containing multibyte character. See also: http://www.mail-archive.com/bash-completion-devel@lists.alioth.debian.org/msg01942.html
Added `_upvars' and `_upvar'. These helper methods aid in passing variables by reference.
Fixed tests when BASH_COMPLETION or TESTDIR contain spaces.
Add a find_unique_completion_pair proc.
