Understood; I am not sold on the whole "warning" business, though.

I think I saw you did 'tr [:upper:]' or something like that in the
patch; we tend to avoid [:class:] and [=equiv=] when not needed,
unless we know that the matching engine used supports them (i.e. it
is OK to use them in Perl scripts and it is OK to feed them to the
wildmatch-based matcher in Git itself, but not in general shell
scripts).  As the values can all be represented in US-ASCII, it
should be sufficient to do "tr 'A-Z' 'a-z'", I would think.
