This is a followup to 3e5ab0a7a9399bb098b9ced46bf3cbf4085c6bab.

* tests/ui.scm ("show-manifest-transaction"): Update regexp.
* tests/guix-package.sh: Adjust Emacs regexp in --with-source test.

Reported by Pierre Neidhardt <mail@ambrevar.xyz>.

* guix/ui.scm (size->number)[unit-pos]: Add #\. to CHAR-SET:DIGIT.
* tests/ui.scm ("size->number, 1.M"): New test.

Fixes <https://bugs.gnu.org/36763>.
Previously, the logical and connecting the regexps did not output the expected
results (introduced in 8874faaaac665100a095ef25e39c9a389f5a397f).

* guix/ui.scm (relevance)
[score]: Change its arguments.
[regexp->score]: New procedure.
* tests/ui.scm ("package-relevance"): Add test.

Signed-off-by: Ludovic Courtès <ludo@gnu.org>

* guix/ui.scm (relevance)[score]: Change to return 0 when one of REGEXPS
doesn't match.
* tests/ui.scm ("package-relevance"): New test.

* guix/ui.scm (string->duration): Add missing '=>' for hours.
* tests/ui.scm ("duration, 2 hours"): New test.

* guix/ui.scm (right-arrow): Call 'set-port-encoding!' to set PORT's
encoding; remove use of 'with-fluids'.  This is for compatibility with
Guile 2.2 where the encoding of string ports is not influenced by
%DEFAULT-PORT-ENCODING.
* tests/ui.scm ("show-manifest-transaction"): Likewise.

* guix/ui.scm (string->duration): Add seconds and hours.
* tests/ui.scm ("duration, 1 second"): New test.

Before that '.log' files for scheme tests were fragmented and not
included in test-suite.log.  This unifies the semantics of SRFI-64 API
with Automake test suite.

* build-aux/test-driver.scm: New file.
* Makefile.am (SCM_LOG_DRIVER, AM_SCM_LOG_DRIVER_FLAGS): New variables.
(SCM_LOG_COMPILER, AM_SCM_LOG_FLAGS): Delete variables.
(AM_TESTS_ENVIRONMENT): Set GUILE_AUTO_COMPILE to 0.
* test-env.in: Silence guix-daemon.
* doc/guix.texi (Running the Test Suite): Describe how to display the
detailed results.  Bug reports require only 'test-suite.log' file.

with error code 77.

This provides the ability to use numbers in package names.

Fixes <http://bugs.gnu.org/19219>.

* guix/utils.scm (package-name->name+version): New procedure.
* gnu/packages.scm (%find-package): Add a FALLBACK? keyword argument.
Use the previous method when no package is found.
