Subject: [PATCH] cracklib: prevent "line out of order" warnings
Workaround for handling excessively long lines in cracklib-words.gz file.
Ensure that all lines read from any words files are truncated to 1023
characters as the cracklib-packer utility (run by the Alpine package trigger)
breaks up long lines on this boundary and processes them separately as if
they were seperate lines and it can potentially generate "line out of order"
warnings.
It also ignores blank lines in word files, this prevents "skipping line"
warnings when blank lines are encountered.
Upstream PR 33 has been raised with this fix.
