No, not intentional.  I simply didn't follow far enough how the string
was used and mistakenly thought it was an entire command.  Thanks for
finding and fixing this.

(It probably would be less error-prone if v_issue_imap_cmd() would be
responsible for adding the extra space in the second branch of the
following if statement:

    if (!cmd->cb.data)
            bufl = nfsnprintf(buf, sizeof(buf), "%d %s\r\n", cmd->tag,
cmd->cmd);
    else
            bufl = nfsnprintf(buf, sizeof(buf), "%d %s{%d%s}\r\n",
                              cmd->tag, cmd->cmd, cmd->cb.dlen,
                              CAP(LITERALPLUS) ? "+" : "");

but that's a design choice that was already in the original version and
I don't care enough to change it.)

ACK.
