boxes.sh grep: Unmatched [ or [^ at egrep '[[:space]]'

[Reini Urban]

Jaro,

Our nice new setup found a problem in the boxes postinstall script:
Package: boxes
	boxes.sh exit code 2
Package: No package
	boxes.sh exit code 2

cd /etc/postinstall
$ ./boxes.sh
grep: Unmatched [ or [^

in grep -E '^[^#]*/|^[[:space]]*$' /etc/preremove/boxes-manifest-from.lst
and it is the [[:space]] part, which is broken. Per man grep it should
work, but I don't know those specialities too well.

$ grep --version
GNU grep 2.6.3
