    Add a debug line when wrapping split-screen chat lines.

    Is this the point when the lost chars problem happens?

    Modified Files:

    Log Message:
    Add error and debug level log messages to private chat

    When reading and writing characters to chat files, log each with a debug-level log message. If a read or a write fails, log with an error-level log message.

    This will hopefully help root-cause and resolve issue #304.

    Don't log debug msgs when reading 0 (\x00) from chat.dab file, expected

    This just resulted in a lot of unhelpful noise in the log output

    Log Message:
    Fix-up the recently-added debug/error log messages

    I didn't look closely enough at which write() call I was instrumenting.
    This is now more useful, though I think we already found the root-cause
    based on different log output ("Unexpected ansi_getxy response").

    Sysop can chat with nodes that aren't logged-in (at logon prompt, new users)

    Be sure to let them select a node even when no nodes are technically "in use". As requested by Nelgin in IRC (what, no gitlab issue?)

    Fix buffer overflow in guru chat parsing engine

    The trigger was this line in the recent change to guru.dat:
    Unrealized potential. :-(

    That open paren was parsed as the beginning of a new guru expression. A very long guru expression that overflowed the stack variable 'str' here.

    Modified Files:
    src/sbbs3/chat.cpp
    Log Message:
    A close-parenthesis in a guru.dat response string would throw-off the parser

    After a negative-match of a Guru expression, we were searching for the next
    '(' anywhere in the subsequent chars of the file rather than just the next
    line that started with an open-parenthesis character.

    This bug was the secondary cause of the buffer-overflow crash addresseed in commit 62e2280e which was triggered by my recent updates to the guru.dat.
