Is this a bug that should be reported against rpm or something else?
I'm certain I've seen it in other man pages, but offhand I can't find
another example.
The man output has formatting commands. Use "man -t rpm | grep -C 10
rpmverbosity" verbosity to avoid feeding those formatting characters
to the grep command.
