implement tty tracking and bump to R41 for feature completeness
...
• tty_fd is now never closed
• new tty_hasstate tracks tty_state (cf. thread around
http://article.gmane.org/gmane.os.miros.mksh/79 and PLD bug)
• as users requested, importing COLUMNS or LINES from the environment
now removes its special-ness as does unsetting it
• otherwise, setting COLUMNS or LINES is honoured until the next SIGWINCH
arrives or change_winsz is otherwise run (e.g. before displaying the
prompt in the interactive command line editing modes)
• SIGWINCH is now honoured before each reading of $COLUMNS and $LINES too
• change the Uhr to match – it no longer calls stty(1) ☺

EXPERIMENTAL optimisation for “sh -c 'foo'” to equal “sh -c 'exit foo'” iff
...
several conditions are met as outlined below; for more background, refer to
http://www.FreeBSD.org/cgi/query-pr.cgi?pr=113860
We don’t yet optimise 「% sh -c '{ echo a; sleep 10;}&'; sleep 1; ps T」 so
the FreeBSD® sh approach cannot work for us, but scanning the “sh -c” argu‐
ment for disallowed characters and, if not, setting a flag that enables the
shell to exec the tree when parsed as TCOM *and not c_trap()* was possible.
Disallowed characters are currently C_QUOTE except space, that is:
Tab Newline " # $ & ' ( ) * ; < = > ? [ \ ] ` |
This should catch all cases of magic, variables, subshells, pipelines, etc.
