Sigh... why do people insist on removing useful comments and leave
their tricky code more obfuscated than it must be??
* test/src/comp-tests.el (comp-tests-type-spec-tests): Add a
comment explaining why the expressions are quoted.  (Bug#51104)

Fix whitespace-tests on macOS

comp-tests.el: Enable compilation again

Rather than disable byte-compilation to circumvent bug#51104,

not end up hardcoded in the `.elc` file.

reason if librsvg happens to return an empty message text.

much the same (bug#57753).

Avoid double svg error reporting and segfaults

vc-retrieve-tag to vc-switch-branch.

* lisp/vc/vc.el (vc-print-branch-log): Fix interactive spec.

For reading vc-read-revision in the interactive spec use the same 'backend'

does (bug#51049).  This is not what it was intended to do -- but
what it intended to do didn't really make that much sense either,
so perhaps the prop should just be renamed :image-only?
