Single line input for psql copy command

I have the following problem:

A database server and another client machine. I have to execute several \copy commands in psql on the client machine to retrieve data and store the output in CSV files. The PostgreSQL COPY command is not an option because it stores the results on the database server, not the client machine. All \copy commands are executed from several files containing SQL commands, which are concated together by a makefile and feeded into psql. So far so good.

My SELECT commands used in the \copy are a bit more complicated and \copy requires to have the entire command on a single line. That can be done in two ways:

- Write the entire command in a single line. But that's hard to debug :-(

- Write the command as i like it and remove the linebreaks before feeding the command into psql.
