Set the maximum size for the busy window in order to cover the full window.

Updated section about filename conventions to include all systems.

Updated documentation about filenames. Environment variables can be surounded by braces or parantheses and one can use (cmd args) for injecting the output of a command into the filename.

Allow specifying just the font size as the font name for HPDF (Qt and Amiga).

Set line width to 5 when drawing the horizontal line separating header and contents in PDF output. This is needed when font embedding is turned on as otherwise, an "empty" line is drawn.

Enable font-embedding when creating PDF files in Qt.

Allow printing, PDF export and text export for select-from-where results that have zero rows. Always print at least 1 page with the column header.

In filenames, first check if $(XXX) refers to an environment variable before trying to execute XXX as a command. On Amiga, do not try to run the command due to the missing popen interface.
