and take ahead parsing collating symbols, equivalence classes and
character classes already (heck my first draft of this already did
better than GNU bash, ksh93 I still don’t grok its code at all)
• not designed to be emitted, only used in comparisons with
other asc() results
• on EBCDIC platforms, the mapping of an EBCDIC octet to their
corresponding ASCII or Unicode/UCS-4 codepoint or, if there
is no mapping, a distinct value above all valid Unicode codepoints
• on nōn-EBCDIC platforms, just the identity mapping of the input
octet into their ord() value
Intended use are ASCII-ish character ops, including ranges (“A-Z”),
mapping from those to the corresponding digit offset, and sorting
of things in an ASCIIbetical way
• make fast character classes even faster by removing the C_SUBOP2 hack
in favour of a separate seldom-used ksh_issubop2 macro (which also
makes ctype() side-effect-safe) which is a slower class (no change there)
• optimise cases of ksh_isalphx followed by a ksh_isalnux loop
(used parsing variable names)
• remove a misleading comment in initctypes() about \0 from pdksh
• rename C_ALPHA to C_ALPHX to make it more clear the underscore is included
• sprinkle a few ord() in there
• add new ksh_isalpha() which tests for [A-Za-z] (slow character class)
• there is no '_:\' drive on OS/2 (which inspired the whole changeset)

initial port to Harvey-OS’ APEX (Ronald G. Minnich, Elbing Miss, Álvaro Jurado)
more from komh’s OS/2 port (KO Myung-Hun)
• if HAVE_STRING_POOLING is set to 1
• if HAVE_STRING_POOLING is set to 2 and not GCC < 4 is used
• if HAVE_STRING_POOLING is not set to 0 and LLVM or GCC >= 4 is used
Closes: LP#1580348
separate the backslash+newline things out of the *.opt files,
logically not 100% clean, but better as it is not generated
content anyway (keeping the one-liners in there for now, even
though more consistent would be shifting them out as well)
