It looks like this is a psql bug which has been fixed recently. I see
the OP's reported behavior on a 9.1.1 client, but in 9.2dev it works
as expected:

test=# \set my_home /home/crazy
test=# \echo :my_home/my-script.sql
/home/crazy/my-script.sql

I don't see the exact commit which fixed this, but I do see some fixes
to psql's lexer done recently, such as
928311a463d480ca566e2905a369ac6aa0c3e210, so maybe this case got fixed
as a nice side-effect.
