New Revision: 191677
URL: http://svn.freebsd.org/changeset/base/191677
Log:
Report the next directory being scanned when a ^T is pressed (or any
SIGINFO). Provides some progress report for the impatient. This
won't report that we're blocking in our walk due to disk/network
problems, however. There's no really good way to report that
condition that I'm aware of...
