Subject: Unified printing of flags.
X-Git-Tag: holmes-import~506^2~110
X-Git-Url: http://mj.ucw.cz/gitweb/?a=commitdiff_plain;h=0734923f3099f9d30cec159a992543cc74ec4964;p=libucw.git

Unified printing of flags.

I've moved format_flags() from idxdump to libucw and used it where possible.
I've also unified the direction in which flag bits are printed, so the order
of the state flags has changed [but I don't think anything relies on it].
