This fixes completing filenames containing single quote (') on bash-4.
Also added emulation of `-o filenames' to _filedir.
Added tests for _filedir.
Fixed array assignment within __reassemble_comp_words_by_ref().
This allows tab-completion of test scripts to run, e.g.:
$ ./run unit/comp<TAB>
$ ./run unit/compgen.exp
Instead of the old way:
$ ./runUnit compgen.exp
The COMP_ settings of the last test of _count_args() were falling through to
the first test of _get_cword(), causing it to fail.
Unset COMP_ variables within the unit tests setup & teardown.
Fixed last test at `_count_args.exp' by solving conflicting settings of
COMP_CWORD and COMP_POINT.
Steps to reproduce the problem:
$ ./runUnit _count_args.exp _get_cword.exp
...
Running ./unit/_count_args.exp ...
Running ./unit/_get_cword.exp ...
ERROR Unexpected output from bash command "_get_cword should run without errors":
bash: $index: substring expression < 0
...
If a word is made up of multiple word separator characters:
$ a b::<TAB> # CWORDS are: a, b, and :: (correct)
__reassemble_comp_words_by_ref() couldn't handle this. It assumed CWORDS were:
$ a b::<TAB> # CWORDS: a, b, : and : (but they're not)
Added test case for this. To run the automated tests:
./runUnit _get_cword.exp
The solution for bash-4 is to remove the colon from COMP_WORDBREAKS:
COMP_WORDBREAKS=${COMP_WORDBREAKS//:}
The workaround for bash-3, or bash-4 with a colon in COMP_WORDBREAKS,
is to call:
__ltrim_colon_completions "$cur"
after completions have been put in COMPREPLY.

in the filename? - Bash FAQ, http://tiswww.case.edu/php/chet/bash/FAQ
Actually enhanced __get_cword3 to _get_cword, and removed __get_cword4.
__get_cword4 could handle chars to exclude from COMP_WORDBREAKS, but
failed with partial quoted arguments (e.g. "a 'b c|", | = cursor
position). This was no problem till bash-4.0.35, because bash < 4.0.35
also returned partial quoted arguments incorrectly. See also:
http://www.mail-archive.com/bug-bash@gnu.org/msg06094.html
Now that bash-4.0.35 returns quoted arguments ok, __get_cword3 is
enhanced to also handle chars to exclude from COMP_WORDBREAKS. Because
__get_cword3 also handles partial quoted arguments correctly, this makes
__get_cword3 suitable for bash-4 as well.
