Or instead of guessing, you could have looked to see where it is
actually used. svn_wc_get_pristine_copy_path() is a public wrapper
around svn_wc__text_base_path(), and is used in only two places, both
in libsvn_client, supporting cat and export of a BASE revision.

Too much detail, in my opinion. 'Remove incorrect statement in
doc-comments' or anything similar would be fine.

I'd also remove the 'This is needed so clients can do diffs' statement,
since this doesn't appear to be true, and even if it was, we shouldn't
try to justify all the possible reasons a client might want access to the
BASE version of the file. Mentioning the word 'BASE' here might be a good
idea too, since 'pristine' isn't immediately obvious as the same thing.
