Good point. Maybe you could have modified the code a little to keep the patterns around and save them  instead of the fully-specified font name, but it's better to be more like WinBoard anyway.

With the changes I made, in the NLS case we end up saving the pattern lists with just the desired pixel size filled in, not a fully-specified font name, since there are multiple fonts in a FontSet (several if not all of which Xaw may be using) and there isn't really a way to save all those names and rebuild the FontSet from them. Normally XCreateFontSet will create the same FontSet next time anyway.

Short comment from the Ionian isle of Kefalonia:

This turned out to be pretty essential when we started saving settings. At
first I naively saved the font variables from appData. But it was the
matched font that would be saved, not the template with all the
wild-cards, meaning that it would have a specific point size. If you would
then later start XBoard with another -size, you would get totally
non-fitting characters with it, because the full specification would
basically disable the entire font-selection process.

So at first I just refrained from saving the -font options altogether.

Then I tried this WinBoard-inspired solution of saving the matched fonts
per size, so that they would not affect any other board size than the one
in force during the original selection process.
