doc/recover.6: Revise synopsis
Tighten formatting: set synopsis syntax characters adjacently to operands. Rename `-d` option argument from "directory" to "playground-directory" for clarity. Set operands more idiomatically. They are not given in pairs; instead "base" can be repeated arbitrarily. See, for example, the POSIX reference page for ls(1). https://pubs.opengroup.org/onlinepubs/9799919799/utilities/ls.html Format ellipsis idiomatically. groff_man_style(7): Notes ... The idiomatic roff ellipsis is three dots (periods) with thin space escape sequences \| internally separating them. Since dots both begin control lines and are candidate end‐of‐sentence characters, however, it is sometimes necessary to prefix and/or suffix an ellipsis with the dummy character escape sequence \&.
