An earlier change to multi-file support stored the actual markers to the beginnings of the transaction/postings.
When reconcile would insert characters it would invalidate those marker and after many items and been
cleared could result in severe misalignment. This change brings back storing the line-numbers as reported by emacs.
ledger-report-save would fail if you entered a new report with a name. It wouldn't save the customization to the disk, and if you tried to save manually it would complain about an identical command.
C-c C-s now bound to ledger-sort-region. ledger-sort-region is smart and
find the beginning of the first xact within the region and the beginning of
the first xact AFTER the region so that it can keep posing structure intact
