[Attn: mercurial maintainer] hg fails with python3.9

[Attn: mercurial maintainer] hg fails with python3.9

[Ken Brown]

/usr/bin/hg specifies /usr/bin/python3 in its shebang, but further down it has

   libdir = '../lib/python3.8/site-packages'

This causes hg to fail as follows if /usr/bin/python3 points to python3.9:

$ hg

   File "/usr/lib/python3.8/site-packages/mercurial/policy.py", line 69, in

During handling of the above exception, another exception occurred:

While uploading fix, I got this:

  ERROR: package 'mercurial' version '5.7-3' is most recent non-test version, but version '6.0-1' is curr:

My mistake. I had the development environment in wrong server, so only 5.7
was in there and I forgot to check the latest in Cygwin.

6.1.1-1 uploaded

Thanks,

No problem.  I'll see if I can improve that error message sometime.

I notice that mercurial appears to be pure python, so maybe we can 
upload it as noarch in future?

Sure. I'll adjust it for the next upload.
