annotate backend/contrib/shpimporter/fixpoints.py @ 8813:8abe94270f32

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Do not filter cross section points for display. Filtering coordinates outside an extent probably aimed at omitting outliers from the diagram. This is obsolete and had the side effect of filtering the important point at x = 0.
