- implement \\
in plain text, identical to \e
as a macro argument, identical to \ i.e. escaping the next character

+- implement blank `Bl -column', such as
+ .Bl -column
+ .It foo Ta bar
+ .El
+
+- explicitly disallow nested `Bl -column', which would clobber internal
+ flags defined for struct mdoc_macro
+- set a meaningful default if no `Bl' list type is assigned
+
+- have a blank `It' head for `Bl -tag' not puke

+- FIXED OpenBSD mdoc.c 1.52 schwarze 16.5.10
+ lines containing blank characters, and nothing else,
in literal context (.Bd -literal):
groff outputs just blank lines "\n"
mandoc outputs blanks to the left margin,
then the number of balnks minus one

+* performance issues
+************************************************************************
+
+Several areas can be cleaned up to make mandoc even faster. These are
+
+- cache `Bd' display types as `Bl' types are cached (this primarily
+ improves code-size by removing the a2disp type functions)
+
+- improve caching mechanism to handle other per-element arguments so
+ that they need not be recalculated between front- and back-ends (also
+ reduces code size and complexity)
+
+- improve hashing mechanism for macros (quite important: performance)
+
+- improve hashing mechanism for characters (not as important)
