[ After not replying to the proper question before, I will try again. :-) ]

The actual stripping of comments in psql is a little more complex.  For
example, this will not strip:
SELECT /* test */ 1;

while this will strip comments:
SELECT 1; /* test */

and leading comments are not stripped either:
/* test */ SELECT 1;

so if the comment is _inside_ a query, it will be OK, but outside and
trailing, psql processes the comment itself so it can display the proper
prompting:
test=> /*test*> test
           ^test*> */
