+Some macros treat ':' as an argument delimiter but others do not. A consequence
+of this is macro arguments which intentionally include a ':' character may look
+like a sequence of multiple arguments but are treated as a single argument by
+macros that don't split their argument on ':'. This tests that we maintain this
+behaviour as we change the way that macros are implemented.
+
+This test installs a binary whose name contains a ':' character and then checks
+that we can look up the binary with the `bin` macro which does not split its
+arguments on ':'.
