[issue1976] shrink-revlog.py fails on Windows

[Pascal Quantin]

New submission from Pascal Quantin <pascal.quantin at gmail.com>:

Now that shink-revlog.py turned into an extension in revision 9d79b8f58bea,
I tried to use it on my Windows box.
It raised the following backtrace:
** unknown exception encountered, details follow
** report bug details to http://mercurial.selenic.com/bts/
** or mercurial at selenic.com
** Mercurial Distributed SCM (version 1.4.2+21-843f6ee6d14b+20100107)
** Extensions loaded: churn, convert, extdiff, graphlog, highlight, mq,
patchbomb, rebase, win32text, svn, shrink
Traceback (most recent call last):
  File "hg", line 27, in <module>

shrink
    os.link(indexfn, oldindexfn)
AttributeError: 'module' object has no attribute 'link'

Obviously os.link is not supported on Windows. Replacing its call by
os.rename allowed to run the extension successfully.

PS: I will wait for a fix before submitting a patch to include this useful
extension in Windows installer
