After implementing timestamps, error data was erroneously persisted. Address
by deleting the state once consumed in constructing the relevant status string.
The buffer age was not working as intended
The fix to exit on error exited overly eagerly
The log replay failed to report a third value if file did not exist.
For certain scenarios (e.g. wcons), having a path to get in and communicate data from the outside.
For starters, have a 'GETWINID' directive for wcons to use to fetch the unambiguous window id
to use for xwininfo tricks. TODO includes concepts from xtcd.pl that enabled things like warr
Previously, the console start path would bail out without consuming the '_requestdone' message.
Correct this by reading until requestdone is seen as required by protocol.
The '.' command would fail to exit the function, causing the 'help' output to occur.
Fix this by having the '.' command processed in the same manner as the rest.
