Zsh and Prezto files don't always reside in `~/`. Instead, they have
a more spec compliant location (`${ZDOTDIR:-$HOME}/`). Make them
unambiguous in the documentation. Likewise, for `$GNUPGHOME`.
Further, add instruction for optionally setting up Prezto in
`$XDG_CONFIG_HOME`.
While at this, also add clarification on relative ordering of some of
the modules, apply more formatting tweaks and doc improvements.
Detect `ls` provided by GNU Core Utilities upfront before applying
the relevant settings and aliases.
The revised logic takes the following aspects into consideration:
- `is-callable 'dircolors'` is not a sufficient test for verifying if
the `ls` in scope is _also_ provided by GNU Core Utilities. `ls` can
continue to be the one provided by BSD Core Utilities because of its
precedence in `$path`.
- The `ls` in scope anyway can be either GNU Utils provided or BSD Utils
provided depending on either `$path` precedence, soft link (via
`ln -s`), or wrapper function (via 'gnu-utility' module).
- So instead of '_guessing_' the possible one, just detect if it is from
GNU Utils and apply the relevant settings and aliases.
- Note that GNU prefixed `ls` (`gls`) is intentionally not honored in
this case to avoid possible conflict/shadowing with other `gls`
callable (can happen if 'git' module is used, for example).
Besides, honoring `gls` would imply we honor other commands (like
`mv`, `rm` etc.) to be consistent. We have a module 'gnu-utils'
dedicated for that after all.
General purpose reformating and rewording in (a few places). This should
also make markdown linting happier.
Prefer back-ticks wherever useful and use `console` for code blocks to
be executed on terminal.
Also, update references links wherever possible (including update from
'http://' to 'https://').
Changes:
- Rename `rsync_scp_wrap` to `noremoteglob` and make it more generally usable
- Enable completion support for commands wrapped with `noremoteglob`
- Tighten up internal variable usages
- Update documentation for 'noremoteglob' function
