Moved making-expected-list-unique out of `match_items()' & `get_hosts()'
into `assert_complete()' because the former are low level functions and
items need not necessarily be unique. They only need to be unique when
we're actually testing *completions*.
This fixes a bug under bash-4 where completing:
scp -F 'spaced conf' <TAB>
causes `dequote' to yield errors:
bash: eval: line 1: unexpected EOF while looking for matching `''
bash: eval: line 2: syntax error: unexpected end of file
The bug occurs because of a bug in bash-4.0, where quoted words are split
unintended, see: http://www.mail-archive.com/bug-bash@gnu.org/msg06095.html
Workaround is now to silence `dequote' in case of errors and wait for bash-4 to
be fixed...
