Hi Kristaps, not sure misc@ is the ideal list for discussing this (as opposed to, say, discuss at mdocml dot bsd dot lv), but as you started here and the topic will soon be finished:

Stuff like \s0 or \s12 may not be documented in the GNU troff manuals - i did not check - but the Nroff/Troff User's Manual by Ossanna, Kernighan, and Ritter, available as part of the Heirloom Documentation Tools, see http://heirloom.sourceforge.net/doctools.html does document it: "Alternatively the point size may be changed between any two characters by imbedding a \sN at the desired point to set the size to N, or a \s1N (1<=N<=8) to increment/decrement the size by N; \s0 restores the previous size." (section 2.3) Oh, and by the way, \s39 appears to be equivalent to \s'36', while \s40 appears to be equivalent to \s'4'0 - that is, in the letter case, the character '0' appears in the output stream, in font size 4pt! But i'm not sure we really need to extend quirk-compatibility down to that level of ugliness. Looks like somebody applied the principle of biggest surprise when designing this. Yours, Ingo
