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.

sshpeer: allow doublepipe on unbuffered main pipe The output pipe does not have manually managed read buffer (actually, no read anything). To also use the doublepipe for outgoing write (useful to consume remote output when pushing large set of data) we need the doublepipe to work on standard pipe too.

sshpeer: allow write operations through double pipe We have a shiny toy, lets make it wider.

sshpeer: rename 'size' to 'data' in doublepipe We are about to add 'write' support, the argument will be either an int or a string.

mq: ban \r and \n in patch names (issue4711) This is at best crazy, and at worst will break things like the series file. Let's just stop the madness.

mq: use %r to format illegal characters instead of manually quoting This will make it easier to ban \r and \n in the next patch and still have a sensible error message.
