.xsh files have non-portable file names

[cjg]

EPrints::DataObj::Document calls EPrints::Probity::create_log with a filename generated from EPrints::Utils::get_iso_timestamp. This filename contains ":" so is non-portable.

If this were changed to another character on all platforms (such as "_"), new filenames would not match old ones but bin/export_hashes would still work. Are .xsh files used anywhere else?

Alternatively the character used could be platform specific, but that would prevent transferring an archive from one platform to another.

This problem now affects EPrints::Time::get_iso_timestamp

I avoid this in my working copy by just regexing s/:/_/g

[cjg]

OK. I suggest we make it a platform specific thing as it's better to cause a (teeny) problem moving over to windows from linux (you could safely just delete them all.

moj fixed this.
