Georg Brandl <ge...@python.org> added the comment:
In util.system(), Mercurial adds its own pair of quotes:
if os.name == 'nt':
cmd = '"%s"' % cmd
That will result in one level of quoting too much.
Now it seems unfortunate that this change was done in a minor version.
It is definitely a bug fix, but one that many users have already worked around,
probably in the same way as Mercurial.
Possible ways to resolve:
* make addition of quotes Python-version-specific in Mercurial
* revert to old behavior in Python 2.7.2 (ugly)
* add a check for quotes around the string in Python 2.7.2, and refrain from
adding another set of quotes
(Adding 2.7 release manager to nosy.)
