>Description:
npfctl errors when adding a single IP address with a /32 mask to a table.

I wrote a script that takes the existing entries of a table with "npfctl table <table> list", compares it with new entries, then combines the 2 into a new table.  "npfctl table <table> list" returns single IP addresses with the /32 mask on it so I had to strip the /32 off of it before re-adding it to the table.

I think it makes sense to have npfctl recognize /32 as valid so what comes out can also go back in.
>How-To-Repeat:
# npfctl table goodguys add 1.2.3.4
npfctl: success
# npfctl table goodguys list
1.2.3.4/32
# npfctl table goodguys list | xargs npfctl table goodguys rem
npfctl: invalid address, mask or table ID
#
