Hi, Hackers.
I propose a small improvement to the psql command.
Currently, psql's help/quit/exit command needs to start from the first position of the prompt.
For example, if you write a command after a space, the continuation prompt
(PROMPT2) is displayed.
---
postgres=> \set PROMPT2 'continue=>'
postgres=> <SPACE>help
continue=>
---
The attached patch allows the command to be executed ignoring leading white spaces.
