This is an EXPERIMENTAL feature, use with care.
To enable long paths support, one needs to do two things:
- build Mercurial with --long-paths-support option
- change HKLM\SYSTEM\CurrentControlSet\Control\FileSystem\
LongPathsEnabled to have value 1.
Please ignore 'warning 81010002: Unrecognized Element "longPathAware"';
it happens because Mercurial uses mt.exe circa 2008, which is not
yet aware of long paths support in the manifest (I think so at least).
This does not stop mt.exe from embedding/merging the XML properly.
Why resource #1 should be used for .exe manifests? I don't know and
wasn't able to find an explanation for mortals. But it seems to work.
