Thanks!

This is not really similar to `substring' as `substring' has totally
different third argument.

Why not simply (> excess 0)? `cl-plusp' is a bit confusing - we
generally avoid cl-lib functions unless necessary. (I've never seen
`cl-plusp' used frequently)

It will be best to write dedicated tests here that will clearly indicate
issues when some non-standard LANG environment is used. The current
failure is rather difficult to debug.
