[ast-developers] Shell option keyword and alias

[Dr. Werner Fink]

Hi,

just a bug report here with ksh Version AJM 94u+ 2012-08-01

$ set -k
$ alias dt=date
autoload='typeset -fu'
command='command '
compound='typeset -C'
[...]
times='{ { time;} 2>&1;}'
type='whence -v'

after `set -k' even a `set +k' does not repair the alias builtin
that is it is impossible to assign a new alias as it always lists
the current aliases.

Temporary disabling the shell option SH_KEYWORD in sh_exec()
in the same as for command line editors does avoid a broken
alias builtin after `set +k' but does not help get the arguments
down to the alias builtin.

The attached patch seems to fix the problem. The test suite is
fulfilled.
