The --remove-chars (or -r) option removes characters from the set of characters used to generate passwords. This feature was suggested in Florian Lohoff in the Debian Bug arguments to remove that would cause the original patch to hang in an infinite loop. The algorithm used is also more efficient than the original patch. Addresses-Debian-Bug: #836334 Signed-off-by: Theodore Ts'o <tytso@mit.edu>
