Re: [PATCH v3] Support ent:relative_path

Martin Waitz [off-list ref] writes:

we could also introduce "<tree-ish>/<path>" for absolute path entries.

When you name the tree-ish with usual "branch name", where does
the branch name end and pathname start?  What happens when there
is an ambiguity, and how costly to detect such an ambiguity to
begin with?
