* guix/scripts/environment.scm (guix-environment): Call 'parse-command-line'
outside of 'with-store'. This allows things like --help to run even if the
daemon is not running.
* guix/scripts/environment.scm (%options): Add "ad-hoc" option.
(show-help): Display help for "--ad-hoc".
(packages+propagated-inputs): New procedure.
(guix-environment): Create ad hoc environment when asked.
* doc/guix.texi ("invoking guix environment"): Document it.
* guix/search-paths.scm (search-path-definition): New procedure.
* guix/scripts/environment.scm (for-each-search-path): Rename to...
(evaluate-input-search-paths): ... this. Remove 'proc' and 'pure?'
parameters, and return directly the list of search-path/value pairs.
(create-environment): Use 'for-each' and 'evaluate-input-search-paths'
instead of 'for-each-search-path'.
(show-search-paths): Use 'for-each', 'search-path-definition', and
'evaluate-search-paths' instead of 'for-each-search-path'.
This allows 'guix environment' to correctly handle non-directory
and/or pattern search-path specifications, such as that for
'XML_CATALOG_FILES'.
* guix/scripts/environment.scm (for-each-search-path): Use
'evaluate-search-paths' instead of 'search-path-as-list' & co.
* guix/scripts/environment.scm (for-each-search-path): Iterate over all
derivation output paths.
(packages->transitive-inputs): Process inputs that specify an output, too.
Appending to "raw" args broke optional parameters in 'guix package -I'
and 'guix package -A', and possibly other places. Therefore, switch to
parsing each set of options on its own and append resulting alists
together afterwards.
* guix/scripts/archive.scm (parse-options-from): Rename from
(parse-options) and add explicit argument. New form of (parse-options)
using its old algorithm via -from function.
* guix/scripts/build.scm: Ditto.
* guix/scripts/environment.scm: Ditto.
* guix/scripts/package.scm: Ditto.
* guix/scripts/system.scm: Ditto.
* tests/guix-package.sh: Add test.
* doc/guix.texi (Invoking guix build): Make it clear that the options
are parsed independently.

* guix/scripts/environment.scm (show-help): Align --pure and
--search-paths with other long options; add 'newline' call before
'show-bug-report-information' call.
