Incomplete work on hardware/media utils

Further minor changes

Merge divergent commits... oops

git-sparse

Added first raku script. git-sparse creates a sparse checkout of a git
repository, creating a new repository if needed.

New shebangs script; fixes to tar utilities and hugo-post script

The shebangs script helps me manage dependency listings.

The tar utilities were failing with to-directory options or passphrase
options containing space characters. The fix requires some unappealing
bash-isms, but at least it works.

hugo-post now will work from the root directory of a Hugo project.

Help and usage messages

Specify that the help option causes the program to exit immediately.

Standardize order of options then positional arguments.

Update usage message

Use standard arg parser

Minor update

Added to vimsplit test suite

Added to mkbak test suite

rmold update

Added test suite.

Corrected the name that rmold would self-report as.

gitstat update

Helptext update and test suite added.

wttr update

Added test suite.

wttr incorrectly advertised support for -V as the short form of
--version.

vimsplit update

Test suite added.

Error messages were being incorrectly suppressed.

Test updates

Added two minor tests for ctdir

Added test suite for enumerate

Rewrote tests with bats

As evidenced by the 11 prior commits, proper testing has revealed a
large number of gaps and inconsistencies in these scripts. bats is a
very capable replacement for the old test suite.

Fix quiet option on whiched and whichvi

Previously the quiet option was suppressing the exit code on these
programs.

Effectively no change

I realized why I was deliberately ignoring the quiet option in these
scripts. It was already being handled in myminiparse.sh.

Helptext updates

The more honest description of these programs is [OPTIONS] before
PROGRAM. Options like quiet and verbose do behave differently if they
follow.
