Note: help and version output are generated by a naïve script which tries a few variants of
<command> --help, <command> -h etc. to find the command's help and version info.
Sometimes it gets lucky, sometimes it doesn't; if the output below looks wrong, it probably is.
gitview -version (return code: 0)
GNU Interactive Tools 4.9.5
gitview -h (return code: 0)
usage: gitview [-hvicbl] file
-h print this help message
-v print the version number
-c use ANSI colors
-b don't use ANSI colors
-l don't use the last screen character
