Hello, When I try to run the example program in the documentation for case, the default case is executed every time:
```
$ cat >match
#!/bin/execlineb -S1
emptyenv
case -N -- $1
{
"\\([fo]+\\)bar\\(baz\\)" { /usr/bin/env }
}
^D
$ match foooobarbaz
$
```
I see this in the release version execline as compiled on my own, as well as in
the version currently in the Void Linux repositories, which uses the release
version of the software and skalibs.
As far as I can tell, matching still works correctly when *not* using
subexpressions:
```
$ execlineb -c 'emptyenv case -N -- apple { "a.*" { /usr/bin/env } }'
#=0
0=a.*
$
```
Though I have hardly tested thoroughly.
I had been secretly hoping for exactly this functionality in execline for a
good while now, so I would appreciate it if I could have a version of the case
command that works properly!
