Checking hg exit code in Windows batch

[Jérôme Godbout]

Just some info that may help, since %ERRORLEVEL% is a pseudo variable,
maybe you can try to use the errorlevel directly. %ERRORLEVEL% is an
equivalent to do the following:
*if errorlevel 1 echo Error*

maybe you can try to test errorlevel instead, maybe %ERRORLEVEL% was
modified into your setup.
You may also tryt o reset the error level before doing the operation you
want to check:
*set errorlevel=0*
*... operation here ...*
*if errorlevel 1 ...*

Maybe that can help find the problem,
Jerome Godbout
