Author: pfg Date: Tue Aug 7 23:03:50 2018 New Revision: 337440 URL: https://svnweb.freebsd.org/changeset/base/337440 Log: Fix printf(1) ignores width and precision in %b format. The precision with behavior is "unspecified" by POSIX (as of 2018), but most implementations seem to have taken it to be treated the same as for "s"; applied after the unescaping. Adopt the same treatment on our printf.
