Bug#864493: notmuch: bash completion eats typed option

[Łukasz Stelmach]

Control: reassign -1 npm 1.4.21+ds-2

Dear Maintainer of the npm package.

The reassignment of COMP_WORDBREAKS variable in
/etc/bash_completion.d/npm causes serious problems described in this bug.

    $ printf "$COMP_WORDBREAKS" | hexdump -vC
    00000000  20 09 0a 22 27 40 3e 3c  3d 3b 7c 26 28 3a        | .."'@><=;|&(:|
    $ COMP_WORDBREAKS="=${COMP_WORDBREAKS}"

Bingo!

    $ fgrep -r COMP_WORDBREAKS /etc

And the answer is:

    /etc/bash_completion.d/npm:COMP_WORDBREAKS=${COMP_WORDBREAKS/=/}


Thank you very much for your assistance. I am reassigning the bug to the
npm package.
