bash glob expands [a-c] to [aAbBc]

[Cédric M. Campos]

Hi, there!

I've realized that bash globbing or glob expansion fails to expand letter ranges as expected. For instance, [a-c] is expanded to [aAbBc] instead of to [abc] and [A-C] to [AbBcC] instead of to [ABC], i.e. small and capital letters are intersperse.

One way to correct this is enabling the bash option "globasciiranges", which is disabled by default. This problem is LOCALE dependent and might vary from one system to another.
