* warnings: fix warnings on newer compilersDan Cross2025-07-241-2/+2
| | | | | | | | | | 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.
* Trivial changes: whitespace and modes.Dan Cross2020-01-101-6/+6
| | | | | | | | | Remote whitespace at the ends of lines. Remove blank lines from the ends of files. Change modes on source files so that they are not executable. Signed-off-by: Dan Cross <cross@gajendra.net>
