This fixes a regression introduced in commit b1edcf34d0.
Also don't use any option after `-R` just to be safe. The zshbuiltins(1)
manual states:
> Only the -e and -n flags are recognized after -R; all other arguments

For sake of simplicity, and also to distinguish warnings from errors.
So now we have:
* errors: output to stderr, are **not** silenced with `-q`
* warnings: output to stderr, are silenced with `-q`
* info: output to stdout, are silenced with `-q`
* solicited output (like help, info, or list): output to stdout, does
not make sense to be silenced with `-q`
We also only have warning in 3 situations so far... :- )
Using the `list` action with `-v` shows all current details for the
existing modules.
Don't try to install or update external modules, since they have an
absolute path instead of a valid URL.
and also simplify code by setting multiple variables at once. This
should make the resulting script a tiny bit smaller, while not
compromising on legibility.
Had to remove ${DIR} before renaming ${dir_new} to ${DIR}.
Also also add ${REV} to the info file, in case we need it in the future,
when extracting Zim's degit as a standalone tool for example.
and rename previous to git.
Tools allow for different install and update scripts. The git tool does
what the previous implementation did (installs and updates using the git
client). The new tool installs and updates with the GitHub API, not
using the git client, but using curl/wget and tar instead.
Closes#373
