Stefan Haller c9c1fb6a0b Add old-file-space patch arithmetic for landing on deletions ... The patch package can already map a patch line index to its new-file line number and back (LineNumberOfLine / PatchLineForLineNumber). The diff-line parser being built on top of this needs the old-file equivalents: a deletion has no distinct new-file position (two consecutive deletions share one), so to land on the exact deletion when diving into staging we have to look it up by old-file line number. Add OldLineNumberOfLine and PatchLineForOldLineNumber as direct mirrors of the new-file functions, counting DELETION+CONTEXT lines instead of ADDITION+CONTEXT.
