[Pkg-javascript-devel] Bug#711810: npm: bash completion script clobbers $COMP_WORDBREAKS

[Jérémy Lal]

Package: npm
Version: 1.4.21+ds-1
Followup-For: Bug #711810

The problem i have with this completion code is that i don't know
which part is actually useful on debian.
I guessed the first part only need to be fixed - but i'm not even
sure it works. I don't know in which cases the @ or = symbols are
significant.
Anyway, here's a start. Anyone with better knowledge of bash_completion
is welcome to help.
