From urandom(4) on OpenBSD For portability reasons, never use /dev/random. On OpenBSD, it is an alias for /dev/urandom, but on many other systems misbehaves by blocking because their random number generators lack a robust boot-time initialization sequence.

now `plass find ^keys' will correctly list only entries that starts with "keys"

previously, `plass tee' was limited to only one line; now it's unlimited. While here, fix the commit message too: checking the existence of the file after creating/overwriting it is stupid.

they're just a glorified `cd'

eq/lt/gt are for string-wise comparisons!

gpg has an annoying "feature": it avoids to overwrite files. If in interactive mode, "gpg2 -o foo" will ask the user whether to override foo or not, otherwise will just refuse to work. not nice. working around this by making gpg2 write to stdout, and redirecting stdout to that file. Then restore stdout for sanity :) While here, also make `writepass' fail if gpg fails.
