Thinking about it again, the pattern matching (already present in
default_src_install of EAPI 4) is brittle and relies on the output
of declare -p whose exact format is undocumented.
Maybe we could change the test for an array to the following?
elif ! declare +a DOCS &>/dev/null; then
This seems to work fine in bash versions 3.2 and 4.2. And behaviour is
well documented in the bash reference manual [1]:
