# File name completion (^X,*) does not mesh well with cd and
# symbolic links. cd does path simplification wrt $PWD before
# doing the actual chdir(), while file name completion does
# not do the simplification. E.g., you are in directory A
# which has a symbolic link to directory B, you create a file
# called foobar and you then cd to the symlink to B, and type
# $ echo ../foo^X
# and the shell beeps at you. Would be more consistent to
# do the completion after simplifing the `$PWD/..'.

description:
Parsing of $(..) expressions is non-optimal. It is
impossible to have any parentheses inside the expression.
I.e.,
$ ksh -c 'echo $(echo \( )'
no closing quote
$ ksh -c 'echo $(echo "(" )'
no closing quote
$
The solution is to hack the parsing clode in lex.c, the
question is how to hack it: should any parentheses be
escaped by a backslash, or should recursive parsing be done
(so quotes could also be used to hide hem). The former is
easier, the later better...

The following command hangs forever:
$ (: ; cat /etc/termcap) | sleep 2
This is because the shell forks a shell to run the (..) command
and this shell has the pipe open. When the sleep dies, the cat
doesn't get a SIGPIPE 'cause a process (ie, the second shell)
still has the pipe open.
NOTE: this test provokes a bizarre bug in ksh93 (shell starts reading
commands from /etc/termcap..)
