add `edit' subcommand to interactively modify an entry It's more or less equivalent to $ cd /tmp $ umask 077 $ plass cat entry > tempfile $ $EDITOR tempfile $ plass tee entry < tempfile $ rm tempfile but way easier. It's also safer because it creates an unique randomly named file set up with correct permissions. Suggested by heph, thanks!

make `plass find' case-insensitive This does not affect `plass cat', `plass tee' etc, only the `find' sub-command. Discussed with heph.

small tweak to the manpage

fix some typo in the manpage

rephrase

remove pass(1) from SEE ALSO Hinting at pass(1) doesn't help with the understanding of how plass works. The hint in EXAMPLES and the HISTORY section are enough.

add missing dot at the end of the sentence

add example: ksh completions for plass(1)

plass: remove the `gen' sub-command; now there is pwg(1)

update the `plass tee' documentation

fix .Ex usage; was missing -std

document the -h flag

add example of plass find | rs(1)

add EXIT STATUS section
