The docs say the errno that fits, Joincol's order, the pane cap, the paste's second Enter, a follower across Restore, and why wc waits

Dogfood round 9's doc findings: ENOENT for a missing pane, file or dump is
right, so the skill says EIO or an errno that fits; Joincol folds into the
column on the right, the joined panes below its own; the skill gives the
64-pane cap; Python's second \r is needed only when the paste lacks a
trailing newline; a log follower loses nothing within a session, but a
Restore hangs it up; and a tag word gets no file argument, as in acme, so
bare wc waits on stdin (pardes has no $%).

 several bound ask which. The tag's own words, `Exec <text>` by name and a

+A tag word runs as acme's does, in the pane's directory with no file named:

 Pane and column command text leave a small gap after their aligned drag grips.
 GUI pane mode symbols are centered by their visible ink; changing the font or
 its size refreshes the cached measurements.
