tg 5743c00a5b add -DMKSH_FAUX_EBCDIC to test the codepaths better 
waking up to: Lanfear - Just Another Broken Shell

tg d658ad626b commit the EBCDIC run-time table conversion code, so it can be reviewed 
XXX there’s still the issue of compile-time character conversion, and
XXX that runtime m̲u̲s̲t̲ use a compatible codepage, which we cannot check,
XXX and that we need the POSIX portable character set mapped, which we
XXX decide to not check (due to the above, mostly)

tg 3dff460cde prepare the new fast character classes, not live yet: need sanity check

things down to short is not possible; we can splurge with 32 bit thus

KO Myung-Hun a5da1fa0b6 main: find a script executed by extproc in current directory first

This is the fix of regression of commit
