TODO note on that `.TS', `.TE' etc. aren't real roff macros and troff

won't recognise them when invoked as e.g. `.   TS' (we, however, do).

+- It should be noted that in mandoc, the TBL macros are interpreted as
+  real roff macros (e.g., `.  TS' is ok), while the troff preprocessor
+  only looks for `.TS' (static string).  This should be noted in the
+  COMPATIBILITY section.  The same applies for nascent `.EQ' (as it is
+  now, `.EN' is processed as a static string).

 - .TP before .SH is still FATAL in man(7)
