sequences supported by GNU awk are not supported yet
xref stuff referenced within manpage in SEE ALSO, add reference to FSF's
"AWK Programming Language"
various other little fixes
actually, awk DOES support RSTART and RLENGTH, remove from list of variables
noticed the number of open files is limited to FOPEN_MAX (20), this should
be made dynamic
* divide text into subsections according to function
* group I/O, math functions together (similarily to how gawk manpage
is structured) and provide easily parsable
list, so that it's much easier to find information about individual
functions
* sort function and variable list by alphabet
to dist/nawk/, since it's not likely mdoc formatted manpage would become
part of nawk distrubution.
Hopefully mdoc macros are used mostly correctly here.
