     gives 3, 4 and 5.  Similarly, a range of 4:2 gives 4, 3, and 2.
 
-ENVIRONMENT VARIABLES
----------------------
-
-HGEDITOR::
-    This is the name of the editor to use when committing. Defaults to the
-    value of EDITOR.
-
-    (deprecated, use .hgrc)
-
-HGENCODING::
-    This overrides the default locale setting detected by Mercurial.
-    This setting is used to convert data including usernames,
-    changeset descriptions, tag names, and branches. This setting can
-    be overridden with the --encoding command-line option.
-
-HGENCODINGMODE::
-    This sets Mercurial's behavior for handling unknown characters
-    while transcoding user inputs. The default is "strict", which
-    causes Mercurial to abort if it can't translate a character. Other
-    settings include "replace", which replaces unknown characters, and
-    "ignore", which drops them. This setting can be overridden with
-    the --encodingmode command-line option.
-
-HGMERGE::
-    An executable to use for resolving merge conflicts. The program
-    will be executed with three arguments: local file, remote file,
-    ancestor file.
-
-    The default program is "hgmerge", which is a shell script provided
-    by Mercurial with some sensible defaults.
-
-    (deprecated, use .hgrc)
-
-HGRCPATH::
-    A list of files or directories to search for hgrc files.  Item
-    separator is ":" on Unix, ";" on Windows.  If HGRCPATH is not set,
-    platform default search path is used.  If empty, only .hg/hgrc of
-    current repository is read.
-
-    For each element in path, if a directory, all entries in directory
-    ending with ".rc" are added to path.  Else, element itself is
-    added to path.
-
-HGUSER::
-    This is the string used for the author of a commit.
-
-    (deprecated, use .hgrc)
-
-EMAIL::
-    If HGUSER is not set, this will be used as the author for a commit.
-
-LOGNAME::
-    If neither HGUSER nor EMAIL is set, LOGNAME will be used (with
-    '@hostname' appended) as the author value for a commit.
-
-EDITOR::
-    This is the name of the editor used in the hgmerge script. It will be
-    used for commit messages if HGEDITOR isn't set. Defaults to 'vi'.
-
-PYTHONPATH::
-    This is used by Python to find imported modules and may need to be set
-    appropriately if Mercurial is not installed system-wide.
