• 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)
• print ulimit -a with the flag, like most other shells do
• move ulimit-1 regression test to ulimit-2 and exclude on Haiku:
it can only set the -n and -V limits AFAICT
• document that some OSes (here: Haiku) can only set the soft limits
(so “ulimit -nS 1024” is okay but -S is required)
• check “ulimit -c 0”, which dot.mkshrc uses, everywhere
(if it errors out, hack around it or stub it out with MKSH_NO_LIMITS)
install both lksh and mksh manpages from Build.sh (Martijn Dekker)
spelling fixes (Larry Hynes)
manpage improvements (Martijn Dekker)
initial port to Harvey-OS’ APEX (Ronald G. Minnich, Elbing Miss, Álvaro Jurado)
more from komh’s OS/2 port (KO Myung-Hun)
set source to NULL only if the memory backing source is actually reclaimed;
fixes segfault due to NULL(+24) pointer dereference reported by Score_Under
(simplified testcase added; thanks!)
• if HAVE_STRING_POOLING is set to 1

Closes: LP#1580348
prodded by izabera and carstenh; resolution is:
• you can’t trim a vector in mksh, still (consider ${@:-1})
• future POSIX will require non-empty “word” for most “op”s
• dissolve in order of standard → extension
• dissolve to prefer “op” over “prefix” where still necessary, mostly
