An exported file was full of blank gaps: a record ran down a dozen lines
and the next appeared to start in the middle of the page. ADDRESS is a
multi-line field by the standard and callbooks and other loggers fill it
that way — "Kabul", four blank lines, "Afghanistan" — and the writer
copied the value out as it stood. The files were always valid, since ADIF
counts bytes; they were unreadable, and so was anything that quoted them.
Line breaks inside a value are now joined with a comma and tabs become
spaces, which is how an address reads on one line anyway. The length
prefix is computed after the flattening, so the record stays exact, and
every path through the writer gets it: the file exports, the uploads and
the record forwarded over UDP.
The changelog's 0.27.15 block also takes back the FT-map hover fix, which
landed after the 0.27.14 release commit and was sitting in that block.
