I just "fixed" this, using the existing idioms available used in mktap, but I
noticed 2 other problems while doing so.
- currently the only idiom for reporting this sort of simple error is "print
'foo'; sys.exit(2)". This isn't really optimal, since we're hopefully going
to be using twisted.tap through a non-commandline interface at some point,
and the failure should be a formattable, self-contained exception.
- the help message for almost every "tap" script is quite long, and so it's
very easy to lose the default error reporting. Perhaps it would be more
useful in the common case to print exception/error information _after_ the
help message, rather than before it, when there is a problem?
