I've looked into this recently. IIUC:
* There has been some limited support expressed for having win32text
look in a normal versioned file for hints about the current repo.
* Once concern here was the fact that such config files are somewhat
'untrusted', but the hg config parsing code has recently been
reimplemented to support the concept of 'trusted' versus 'untrusted'
options. I'm not sure what this means in practice though.
* There isn't currently much activity on win32text. None of the core hg
devs seem to use Windows, so while they are receptive to Windows
patches, it might be necessary to be quite noisy to get attention.
I recently submitted some changes to the filtering for Windows which
were accepted without any angst, and the ability to use a versioned file
for per-repo rules is something I'd like too. I believe that if a few
Windows users got together and agreed on both semantics and
implementation we could get such an enhancement landed in the core of hg...
