for function implementing a particular builtin to struct builtin
and to write document file name to `handle' member of struct builtin
- no longer writes separate helpfiles; that is left to gen-helpfiles
2/8
---
subst.c
- make sure last_command_exit_value is set to a non-zero value before
any calls to report_error, since `-e' set will short-circuit
report_error. Fixes bug reported by Ewan Mellor
<Ewan.Mellor@eu.citrix.com>
variables.c
- make_local_array_variable: added second argument; if non-zero,
function will return an existing local associative array variable
instead of insisting on an indexed array
variable.h,subst.c
- make_local_array_variable: changed prototype and caller
builtins/declare.def
- declare_internal: add second arg to call to make_local_array_variable;
making_array_special, which indicates we're processing an
assignment like declare a[b]=c. Fixes seg fault resulting from
a being an already-declared local associative array variable in a
function. Ubuntu bash bug 928900.

# Subject: A Bash source code example
# From: Eric Sanchis <eric.sanchis@iut-rodez.fr>
# To: chet.ramey@case.edu
#
# Using Bash everyday, I developped an enhanced implementation of the
# cd/dir functions described in the Bolsky & Korn book, which
# illustrates several specific Bash syntax elements.
#
# It works fine with a non empty CDPATH and cdable variables. In
# addition, a directory name is indexed only once into the stack.
#
# If you find this code snippet useful, would it be possible to include
# it into the bash-doc section of future bash packages ?
#
# Sincerely yours,
#
# Eric
# IUT Rodez
# University of Toulouse (France)
###
# Another implementation of the directory manipulation functions
# published in the Bolsky & Korn book : "The new Korn shell" :
# cd, to change current directory
# d, to display the stack content
# Eric Sanchis (eric.sanchis@iut-rodez.fr), 2012
