Currently this is the output when looking for the help of, say, the $EMAIL var:
------
screened $ darcs help environment EMAIL
DARCS_EMAIL and EMAIL:
Each patch is attributed to its author, usually by email address (for
example, `Fred Bloggs <fred@example.net>`). Darcs looks in several
places for this author string: the `--author` option, the files
`_darcs/prefs/author` (in the repository) and `~/.darcs/author` (in your
home directory), and the environment variables `$DARCS_EMAIL` and
`$EMAIL`. If none of those exist, Darcs will prompt you for an author
string and write it to `_darcs/prefs/author`. Note that if if you have more
than one email address, note that you can put them all in `~/.darcs/author`,
one author per line. Darcs will still prompt you for an author, but it
allows you to select from the list, or to type in an alternative.
Unknown environment variables:
screened $
------
Note the last line reading 'Unknown environment variables:'. This line is
handy when looking for help about a variable unknown by darcs:
------
screened $ darcs help environment EMAIL foo
DARCS_EMAIL and EMAIL:
[...]
Unknown environment variables: FOO
screened $
------
but seems a bit ugly when no "unknown" variable has actually been passed to the
command line.
The attached patch displays that last line only when it is actually needed.
1 patch for repository http://darcs.net:
Wed Dec 19 01:05:18 CET 2012 Gian Piero Carrubba <gpiero@rm-rf.it>
* avoid displaying 'Unknown ...' in the output of `darcs help environment`
when no unknown variable has been feeded.
