Initial patch by Bruno Piguet.

This is implemented as if a useful .netrc file could exist without passwords,
which is possible in the general case; but in fact our netrc implementation
does not support it.  Fixing that issue will be an enhancement.

Patch by Xuanji Li.

The patch fixes some of the problems on Windows. It doesn't introduce
addition problems on Linux.

There's one major and one minor category still unfixed:
doctests are the major category (and I hope to be able to augment the
refactoring tool to refactor bona fide doctests soon);
other code generating print statements in strings is the minor category.

(Oh, and I don't know if the compiler package works.)

Let netrc handle entries with login fields (mail servers for instance)
by having login default to ''.

Backport candidate.

Expanded the range of allowable characters to include ascii punctuation.
Allows resource files to have a larger character set for passwords.
(Idea contributed by Bram Moolenaar.)

   * 'macdef' (macro definition) wasn't parsed correctly
   * account value not reset for a subsequent 'default' line
   * typo: 'whitepace' -> 'whitespace'

Bugfix candidate.

(as it is often not on Windows). The code was always designed so that it
would raise an IOError if there was no .netrc. But if there was no $HOME
it would return a KeyError which would be somewhat unexpected for code
that didn't know the algorithm it used to find .netrc. The particular
code that triggered this problem for me was ftpmirror.py which handled
the IOError gracefully, but not the KeyError.

Neil Norwitz's PyChecker.

Always has the lineno and filename of the source text.

Use != instead of <> since <> is documented as "obsolescent".
Use "is" and "is not" when comparing with None or type objects.

Here is batch 2, as a big collection of CVS context diffs.
Along with moving comments into docstrings, i've added a
couple of missing docstrings and attempted to make sure more
module docstrings begin with a one-line summary.

I did not add docstrings to the methods in profile.py for
fear of upsetting any careful optimizations there, though
i did move class documentation into class docstrings.

The convention i'm using is to leave credits/version/copyright
type of stuff in # comments, and move the rest of the descriptive
stuff about module usage into module docstrings.  Hope this is
okay.
