+# groff-1.22.3 defects:
+# - .SH without args just before EOF causes two additional blank lines.
+# - Empty .SH heads cause additional vertical spacing.
+# - If .TP or .IP breaks .SH, the tag becomes bold.
+# - If .HP breaks .SH, a line is broken after the next input line.
+# - If .RS/RE/nf/fi breaks .SH, the next input line becomes bold.
+# - .UR does not break .SH.
