Also prevent installation of the git.1 man page and avoid installation of
bin/git in a simpler way.

Take maintainership.

After my latest updates this port no longer installs a program by the
name of git, thus remove conflicts with git and cogito.

Update to version 4.9.5 which has some portability issues which I reported
fixed, and some minor enhancements like filetype info for many more file
extensions and gitaction which supports xdg-open, kfmclient and exo-open.

Update to gnuit version 4.9.4 now that the project is active again, up
from the old version 4.3.20 dating back to 2000 which was still called
git.

Most configuration files, environment variables, the HTML documention,
subdirectory names, etc have been renamed to carry gnuit instead of git
in their names.  Support for large files has been improved, new terminal
types rxvt-unicode, linux-m, cygwin, and Eterm, have been added, and
many bugs have been fixed.

The git file manager is now called gitfm, there is no longer a command
called git.  Among others this helps reduce confusing with devel/git.
