- Add upstream patches
* bash52-003
Command substitutions need to preserve newlines instead of replacing them
with semicolons, especially in the presence of multiple here-documents.
* bash52-004
Bash needs to keep better track of nested brace expansions to avoid problems
with quoting and POSIX semantics.
* bash52-005
Null pattern substitution replacement strings can cause a crash.
* bash52-006
In interactive shells, interrupting the shell while entering a command
substitution can inhibit alias expansion.
* bash52-007
This patch fixes several problems with alias expansion inside command
substitutions when in POSIX mode.
* bash52-008
Array subscript expansion can inappropriately quote brackets if the expression
contains < or >.
* bash52-009
Bash arithmetic expansion should allow `@' and `*' to be used as associative
array keys in expressions.
