crecord: fix three typos introduced while moving crecord into core When moving crecord to core, I did a search an replace to remove all of the variable with caps letter. Doing so, I unfortunately changed some commands with capital letter shortcut to their lowercase counterpart. I fixed one of these cases in 093d38165e5a. This patch fixes all of the remaining cases.

revlog: move size limit check to addrevision This lets us add the name of the indexfile to the message.

sshpeer: also use doublepipe for client to server communication This will allow even more real time output when the server issue output in the middle a stream push.
