Just FYI: Ah, at last some clarity!
>From the bash 3 manual:
COMP_WORDS
An array variable (see Arrays below) consisting of the
individual words in the current command line. The
words are split on shell metacharacters as the shell
parser would separate them. This variable is
available only in shell functions invoked by the
programmable completion facilities (see Programmable
Completion below).
>From the bash 4 manual:
COMP_WORDS
An array variable (see Arrays below) consisting of the
individual words in the current command line. The
line is split into words as readline would split it,
using COMP_WORDBREAKS as described above. This
variable is available only in shell functions invoked
by the programmable completion facilities (see
Programmable Completion below).
The workaround used by the bash-completion scripts is to paste words
from COMP_WORDS together (in _get_comp_words_by_ref).
If only the NEWS file had mentioned it. :)
