 769932 yrc_minor_char_refactors jfw Use backspace character code from yterm rather than showing it in long form. Replace char_range() with simple character classifier functions (consistent with the existing ones and potentially faster than string membership tests). Add citations for some strange IRC character classifications (which came up when looking into how to delimit completion prefixes).
 769934 yrc_completion jfw Implement tab completion for nicks, channels and slash commands. Relatedly: factor out the now common case of inserting multiple characters into the prompt at once, as insert_multi; correct rfind_word_start and find_word_end to always return a valid cursor position (empty returns previously happened to work due to obscure details of None handling); turn the leading slash into a proper part of slash command names, facilitating completion and better distinguishing them from keyboard commands. (Slash commands without parameters could in theory still be given key mappings, but the normal keyboard editing & scrolling commands make little sense to type at the prompt and are no longer recognized there.)
 769938 yrc_net_level_commands jfw Implement /close-net and /reconnect commands, and straighten out which commands can take a part/quit message. A reliable QUIT message *could* be implemented for /disconnect and /close-net (unlike for /quit), so make space to add it there by dropping the optional network name argument from /disconnect, which I found to be more confusing than helpful anyway.
+769940 yrc_connect_join_streamlining jfw Switch to network window on connect and channel window on join. Remove self-generated join/part info messages which route distractingly to the network window (the more useful server confirmations still show in the channel's own window and log). Send a new USER command when changing nick in the connected-unregistered state, since I found it necessary for multiple server implementations when nick is in use.
