This space is necessary for proper expansion of the parameter. The
\set-Command concatenates all its arguments after expansion:
--8<---------------cut here---------------start------------->8---
scratch=# \set HISTFILE .psql_history-:DBNAME
scratch=# \echo :HISTFILE
.psql_history-:DBNAME
scratch=# \set HISTFILE .psql_history- :DBNAME
scratch=# \echo :HISTFILE
.psql_history-scratch
scratch=#
--8<---------------cut here---------------end--------------->8---

I went for bash's behaviour back then, since we copied bash's
semantics with the other history options too.
