>Description:
With the commit of revision 1.15, the db(1) command is broken when selecting a single key:

$ db/db -N hash hash.db localhost
db: Error reading key `localhost': Invalid argument

The invalid argument comes from hash_seq() in src/lib/libc/db/hash/hash.c, which checks for the flags being R_FIRST or R_NEXT. db_get() calls it with R_CURSOR, which works fine for a BTree database but not for hash-database.

>How-To-Repeat:

>Fix:
Backout of 1.14.
