While reading code in libsvn_fs_base/tree.c today, I noticed something.  The
txn_body_apply_textdelta() and txn_body_apply_text() functions both register
`changes' table entries for textual modifications before those mods happen,
which is unlike the way other functions register `changes' table entries (after
the operation has successfully completed).  I have reason to believe that it
might be possible to, then, commit revisions to Subversion (programmatically)
which claim that certain files' text were changed when, in fact, those changes
were never finalized in the repository.
