a99bb8baa0 quote the &, for POSIX: 
An  ordinary  character  is  a  pattern  that  shall  match itself. It can be any
   character  in  the  supported  character  set except for NUL, those special shell
   characters  in [199]Quoting that require quoting, and the following three special
			⇓
   The  application  shall  quote  the following characters if they are to represent
   themselves:

|  &  ;  <  >  (  )  $  `  \  "  '  <space>  <tab>  <newline>

4310e75f75 make tmux hack workable for now (libtermcap is… ugly) 
• track $TERM for the types tmux uses /^screen(-.*)?$/
• when tmux is in use (or GNU screen, really), use the, now
  hardcoded, clear-to-EOL string; otherwise, use the old behaviour
• drop unnecessary x_e_rebuildline()

carefully tested to behave no worse than R52b

c3e794c4d0 rework string pooling; disable our own (rely on compiler’s)… 
• if HAVE_STRING_POOLING is set to 1

• if HAVE_STRING_POOLING is not set to 0 and LLVM or GCC >= 4 is used

e0e63c65e6 fix issues with home directory replacement, from Torsten Sillke: 
• if $PWD = ${HOME}foo, no longer show as ~foo in PS1

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
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

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)
