Perhaps the simpler way to obtain the content of an old version of a
file is (ab)using the diff command in darcs, like in:
$ darcs diff --diff-command 'cat %2' --match "..." somefile.ext
The trick here is that you can specify an external "diff" program that
is executed by darcs to compute the comparison between the two versions
of a file: by specifying "cat %2" you simply obtain the content of the
second one (although it comes out with a newline appended to its end).
hth,
ciao, lele.
