Previously, service descriptions appeared in both guix.pot and
packages.pot, but only translations of packages.pot were used.
Now, translations are only done with guix.pot.
This is better, because translators are more likely to translate
guix.pot, and is also easier, because files in gnu/{home/,}services
need to be in po/guix/POTFILES.in anyway and po/guix/Makevars
already acts on the 'description' keyword because of lint checkers.
* guix/scripts/home.scm (service-type-description-string):
Use translations from guix.pot.
* guix/scripts/system/search.scm (service-type-description-string)
(service-type->recutils): Likewise.
* po/packages/POTFILES.in: Move files in gnu/services to ...
* po/guix/POTFILES.in: ... here.
* guix/ui.scm (package->recutils): Add #:highlighting parameter and use it.
(display-search-results): Add #:regexps parameter; call
'colorize-full-matches' and pass #:highlighting.
* guix/scripts/package.scm (process-query): Pass #:regexps to
'display-search-results'.
* guix/scripts/home.scm (search): Likewise.
* guix/scripts/system/search.scm (service-type->recutils): Add #:highlighting
parameter and use it.
* guix/scripts/system/search.scm (service-type->recutils): Highlight the
value of the 'name' field.
* guix/ui.scm (package->recutils): Likewise for 'name' and 'version'.
This affects the output of 'guix show', 'guix search', and 'guix system
search'.
* guix/ui.scm (hyperlink, supports-hyperlinks?, location->hyperlink):
New procedures.
(package->recutils): Add #:hyperlinks? and honor it.
(display-search-results): Pass #:hyperlinks? to PRINT.
* guix/scripts/system/search.scm (service-type->recutils): Add
#:hyperlinks? and honor it.
* guix/ui.scm (display-search-results): New procedure.
* guix/scripts/package.scm (find-packages-by-description): Remove
'unzip2' call and return a list of pairs.
(process-query): Change to use 'display-search-results'.
* guix/scripts/system/search.scm (find-service-types): Remove 'unzip2'
call and return a list of pairs.
(guix-system-search): Use 'display-search-results'.
