When adding a value containing an equals sign to an indexed array, the
left side is treated as an index if it looks like [N]=val and N is
numeric. SC2191 currently warns about anything that looks like key=val
even though non-numeric values of key will never be treated as an index.
This causes spurious warnings for the common pattern of building up
program arguments in an array, such as:
args=(
--dry-run
--in="${my_var}"
--out=/some/path
-f
)
/bin/program "${args[@]}"
Since only numeric expressions can be a valid index for an indexed
array, only emit SC2191 if the left side of a literal string containing
an equals looks numeric. Other more complicated constructs should still
warn because shellcheck doesn't know if they may evaluate to a numeric
result. Associative arrays still warn because a non-numeric left side
is a valid subscript.
