tg c3e794c4d0 rework string pooling; disable our own (rely on compiler’s)… 
• 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

tg 8370c0dd4d experimentally use MKSH_CLRTOEOL_STRING instead of lots of spaces followed 
by lots of backspaces for many clearing scenarios; requested by tmux user
slagtc on IRC

tg a41a62dad7 efficient $(<<<foo) and $(<<EOF … ) implementation, requested by izabera 2016-06-26 00:44:59 +00:00

tg e4f55499c0 hexdump the NUL away 2016-06-26 00:04:30 +00:00
tg df1d7339be I hate our patch(1), it’s not NUL-safe… 2016-06-26 00:00:53 +00:00
tg 262ae5a436 fix most of the ambiguous ${[prefix] var [op [word]]} corner cases 
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

tg 8d811d19d4 typo, found by Joerg Schilling 2016-05-31 19:59:53 +00:00
tg 9ab9ee194c fix shf.c-internal buffer overread on printing digits, 
introduced by the utf_skipcols()-related fixes, more
specifically the check for combining multibyte characters
past end of given width (bogus mixed-up semantics we have here)
by reïntroducing the NUL byte from commitid 1005474EE1E4024A4E4
 2016-05-17 15:36:35 +00:00
tg 55e51d9580 add, with a warning, regression testcases for: 
• trailing combining character
• ${!#} and friends

the warning is: pid_t is signed (so PIDs could be negative) and may be
rather long, in some cases even longer than a C “long”; we’ll need to
handle this by adding checks (sizeof pid_t=gid_t, sizeof pid_t must be
either mksh_ari_t or u_short) and code (always print $$/$! as unsigned,
set unsigned attribute on $BASHPID and friends)

tg 8e7abc48eb head(1) is not portable (-n 1 not præ-POSIX/ancient, -1 not busybox)

• change cat loader to look for existence, FPATH included, before
  ditching the builtin; note that in manpage
