Hmm, so "deepen 10-by-the-way-let-me-tell-you-something-else" was an
acceptable input that some (third-party) version of "git fetch"
could have used, but now we are rejecting it.
That "let me tell you something else" part wouldn't have reached
outside this code, so it is inconceivable that anybody would relied
on that looseness as a "feature", so the only practical risk would
be if somebody wrote a protocol driver, mumbling "on the Internet,
the end of line is CRLF, just like SMTP does", that sends a "deepen
10<CR><LF>". We used not to notice, but now we reject such a
reimplementation of Git.
