Jonathan Nieder abe27c0cbd vcs-svn: guard against overflow when computing preimage length ...

Signed integer overflow produces undefined behavior in C and off_t is
a signed type.  For predictable behavior, add some checks to protect
in advance against overflow.

On 32-bit systems ftell as called by buffer_tmpfile_prepare_to_read
is likely to fail with EOVERFLOW when reading the corresponding
postimage, and this patch does not fix that.  So it's more of a
futureproofing measure than a complete fix.
