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.
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://').
We now allow multiple paths (files/directories) to be archived in
one shot. Validation of the target path(s) is now delegated to the
actual archive helper.
* archive: fix unrar check when using unrar-free
unrar-free returns the error code 1 when run without arguments, thus
failing the presence check. Replacing the current presence check with
(( $+commands[unrar] )) fixes the problem.
* archive: add unar support for lsarchive and unarchive
No `archive` support with unar.
unrar and rar will discard everything up to the file name when extracting
with `e`. This breaks extraction of archives that have files with duplicate
file names and ones where the paths are important. The `x` command
extracts with the full path instead.
