Arg. It's `funny' you talk about this, since this week-end I fell on
this in the documentation:
@node Portable Shell, Multiple Cases, Run Time, Writing Tests
@section Portable Shell Programming
When writing your own checks, [...] You should not use shell
functions, aliases, negated character classes [...]
and was wondering when someone would complain. You're too fast for me
:)
What do you think? Personally, I am not against giving a chance to
`[!...]', but it has to be heavily tested. Is there anybody who knows
more?
The test case is
case enable_foo in
*[!a-zA-Z0-9_]*) echo Fail;;
*) echo OK;;
