Checking hg exit code in Windows batch

[Jérôme Godbout]

Hi, I tried with mercurial 3.0.1, it worked for me
c:\MyProject> hg update
0 files updated, 0 files merged, 0 files removed, 0 files unresolved

c:\MyProject> echo %ERRORLEVEL%
0

c:\MyProject> hg update -r toto123
abort: unknown revision 'toto123'!

c:\MyProject> echo %ERRORLEVEL%
255

You may want to update to 3.0.1 or above to solve your problem. Haven't try
into a batch.
