Dan Cross 4089e29e89 warnings: fix warnings on newer compilers
Mostly turning the crank on fixing simple warnings: arrays, for
instance, can never be nil.  A couple of pointers should have been
initialized to `nil` before being tested.

Some logic in `troff` was simplified: basically, an `if` statement had
a condition that must have always been true if that section of code
were being executed at all.

This is a port of many Plan 9 libraries and programs to Unix.

Installation

To install, run ./INSTALL. It builds mk and then uses mk to run the rest of the installation.

For more details, see install(1), at install.txt in this directory and at https://9fans.github.io/plan9port/man/man1/install.html.

Documentation

See https://9fans.github.io/plan9port/man/ for more documentation. (Documentation is also in this tree, but you need to run a successful install first. After that, "9 man 1 intro".)

Intro(1) contains a list of man pages that describe new features or differences from Plan 9.
