Detailed Description

Regression test for a plain .mac file surviving wxMaxima's open/save round-trip byte-for-byte, exercising the same code Worksheet::ExportToMAC() and MaximaFileIO::OpenMACFile() use (Format::TreeToWXM() with wxm=false and Format::ParseMACContents()).

Before EditorCell kept '\t' as a real character, every tab in a loaded .mac file was silently rewritten to 1-4 spaces the moment it reached an EditorCell (EditorCell::TabExpand(), now gone) - so opening a hand-written or externally generated .mac file with tabs and immediately re-saving it produced a byte-different file. This pins that a tab used for interior alignment in a code cell survives unchanged.
