It seems like git-cvsserver doesn't know the CVS special case that, if the 
client has removed the file from the working directory (but not called 
"cvs remove"), this means to revert it to the server's version. I think 
that the condition around line 843 needs to exclude this case, and it 
needs to get to line 892 instead, but I can't even fake perl to fix it.

I can confirm the bug. Will look into it a bit and see whether I can
come up with a fix.

Only send a modified response if the client sent a
"Modified" entry. This fixes the case where the
file was locally deleted on the client without
being removed from CVS. In this case the client
will only have sent the Entry for the file but nothing
else.

 We really, really need a test suite for cvsserver...
 I've tested this as good for regressions as I could
 think of but am still unsure about it.

This would make the modified response go away, but would it
cause a fresh re-checkout to happen?

It falls through into the appropriate case, evidently. At least, it seems 
to resolve my issue.

Yeah, the rest of the code handles this case correctly if
it actually gets the chance to do so.

Ack. With this, git-cvsserver matches cvs's behaviour. The only
difference is that cvs also spits out

  E cvs update: warning: $path was lost

cheers,

My cvs client says:

cvs update: warning: $path unexpectedly disappeared

I'm not sure if something suitable is generated client-side in general, 
but mine seems to.
