0.4.0

Breaking Changes

• Arrays elements are now a tuple of (index, value), instead of just value.

  This is necessary because Bash arrays can be non-contiguous.

Fixes

• Support for arrays in Bash 5.2.

• Documentation in long_doc is now a single string.

  The previous implementation put each line in its own element of the array, but this method is incompatible with gettext, since empty strings has a special meaning. See #4.
