Comment 5 for bug 120687

@Dirk: If you look at the /usr/share/doc/bash/COMPAT.gz file, $13 states:
[...]
The portable way to specify upper case letters is [:upper:] instead of A-Z; lower case may be specified as [:lower:] instead of a-z.
[...]

The default for /bin/sh in ubuntu is dash, which seem to behave like older versions of bash (and other shells, e.g. zsh should behave like bash now), that is ignoring the LC_COLLATE environment-variable, which results in shell scripts using the [A-Z]-thing or the like are not destroying anything if it is calling /bin/sh and not /bin/bash, of course.

I do not like the Idea of changing LC_COLLATE, especially for non-english environments.
