Re: [Caml-list] ocp-indent beta release

[Louis Gesbert <gesbert@antislash.info>]

You can get this behaviour with `ocp-indent --config with=3,match_clause=4`

The default behaviour was chosen to reflect the most common current indentation 
practices (and the guidelines, 
http://caml.inria.fr/resources/doc/guides/guidelines.en.html) ; I guess it was 
found that indenting the | doesn't improve readability and makes you run into 
the right margin more quickly.
