Uppercase hex format?

[Rik]

All,

When using "format hex" the output uses lowercase letters a-f to represent
10-15.  This is fine, and compatible with Matlab.

However, in my background as an electrical engineer, I prefer to see this
as uppercase letters A-F.  Is there any interest in extending Octave to
support this?

We already have forms like "short e" and "short E" which switch the
exponent in scientific notation from lower case to upper case.

I made a rough patch which uses "format HEX" to switch to uppercase letters
and it is as simple as adding the flag std::ios::uppercase to the output
stream operator '<<' in C++.
