[plt-scheme] ignoring metadata

You can do (read-line) three times and throw away the results (but
there may be a different number of lines in some future version
(hopefully not ...) so I'd suggest doing some checking, like looking
for ";" at the start of the first two and "#reader" at the start of
the third).
