[PyPy-issue] [issue590] Add Mercurial version information to sys module

[Dan Villiom Podlaski Christiansen]

New submission from Dan Villiom Podlaski Christiansen <danchr at gmail.com>:

If PyPy is built from a Mercurial checkout, it should be able to show information about where it was 
checked out. As part of the CPython migration, a patch has been posted.[1] Applying this patch yields 
these results:

$ grep HG Makefile
HGVERSION=      hg id -i $(srcdir)
HGTAG=          hg id -t $(srcdir)
HGBRANCH=       hg id -b $(srcdir)
	      -DHGVERSION="\"`LC_ALL=C $(HGVERSION)`\"" \
	      -DHGTAG="\"`LC_ALL=C $(HGTAG)`\"" \
	      -DHGBRANCH="\"`LC_ALL=C $(HGTAG)`\"" \
$ ./python.exe -c 'import sys; print(sys.subversion); print(sys._mercurial)'
('CPython', 'branches/release27-maint', '')
('CPython', 'add-hg-build-id.diff qbase qtip tip', 'a40affe1a0c3')

(HGPLAIN=1 should probably be specified in the environment as well.)
