Hello John,

I found that my patch to implement locale support in sscanf/fscanf was not
complete. Beside a call to "imbue" in src/file-io.cc, the file
src/oct-stream.h is also modifled in order to daisy-chain the imbue function
to the underlying layers, i.e. std::stream.

I enclose the full patch, ported to this 3.5.90 version. Missing for now:
- updating the doc
- handling the case where the locale string is bogus

The purpose is to get 1.2 as the result of  sscanf('1,2', '%f', 'fr_FR')
instead of 1. The latter is obtained by using the default locales, i.e.
sscanf('1,2', '%f', 'C').

This patch add a new behaviour, while staying totally compatible with the
established interface. Its use should be thus transparent and should not
break legacy code.

I'm awaiting such locales support in order to release a new version of my
"dataframe" octave-forge package.

Best regards
