tests: document a known failing interaction between narrow and lfs
This is one of the two remaining aborts I found looking into issue5794. I've
got no idea what's wrong with the hook, since the changes there fixed the other
two problems noted in that bug report. It seems like it might go away when the
narrow issue is fixed, but let's make sure this doesn't get lost.
The stacktrace for the hook seems to indicate that the missing file *is* in ctx:
remote: Traceback (most recent call last):
remote: File "c:\Users\Matt\projects\hg\hgext\lfs\__init__.py", line 253, in checkrequireslfs
remote: if any(f in ctx and match(f) and ctx[f].islfs() for f in ctx.files()):
