+ - loc = locality of the issue

+Several areas can be cleaned up to make mandoc even faster. These are
+
- improve hashing mechanism for macros (quite important: performance)
- improve hashing mechanism for characters (not as important)
- the PDF file is HUGE: this can be reduced by using relative offsets
+- instead of re-initialising the roff predefined-strings set before each

************************************************************************
* structural issues
************************************************************************
+- Improve -O suboption parsing. Do it in the main program such that
+ errors can be reported. Pay attention to distinguishing the
+ mandoc(1) and apropos(1) styles of both options.
+ loc ** exist * algo ** size ** imp ***
+
+- Use libz directly instead of forking gunzip(1).
+ Suggested by bapt at FreeBSD among others.
+
+- We use the input line number at several places to distinguish
+ same-line from different-line input. That plainly doesn't work
+ with user-defined macros, leading to random breakage.
+
- Find better ways to prevent endless loops
in roff(7) macro and string expansion.
-
+
- Finish cleanup of date handling.
Decide which formats should be recognized where.
Update both mdoc(7) and man(7) documentation.
