I ended up using $PWD in that script, but this issue is a 'gotcha' when
porting from sh/bash. Maybe documenting it is enough.
The problem with detecting the terminal and doing something different is
that it is hidden and non-obvious behaviour, which makes debugging
scripts frustrating ("why does it work in my terminal but breaks in my
script?? it's the same [EMAIL PROTECTED]"), and breaks the idea that scripts
are
just the same as the command line, except longer and spanning multiple
lines.
