Done now. But to be honest I don't understand why you pointed me to
it. Anyway,

I didn't mean isalnum *alone*. It was meant to replace just the tests
I quoted. And I specified std::locale::classic() (aka "C" locale).

This just to set the records straights, as the whole affair is no big
deal and you are very busy with more important things. Note that I
don't know how "ASCII" got in here, but if the issue is VC++ warning
C4819 then it refers to the "ANSI" codepage (Windows-1252).

In the end, source files should IMHO stick to the 96 characters of the
basic source set. Plus carriage return :-)
