Re: Some (small) problems

Incidentally, if you set PS1 as ...

PS1='[$( X=${PWD#$HOME}; [ "$X" = "$PWD" ] || X="~$X"; printf %s "$X")]; '

then you get the same effect as the version you used,
but without running any external programs, and with just
one fork (for the command substitution itself), instead of 3 or
something..   It probably makes little difference (performance of
interactive prompting isn't usually critical), and the pwd|sed
version is probably easier to understand, but just in case...

ps: It turns out this also works around the bug that was there,
though I have not looked closely to see why, but unless you care
to use it until you get a fixed sh, that's mostly irrelevant.
