- expand_string_for_rhs: now takes an additional PFLAGS argument from
|

its caller (one so far); passes that through to call_expand_word_internal
|
||||
as W_ASSIGNRHS. Fixes bug reported by Martijn Dekker
|

<martijn@inlv.org>
|
||||
- expand_string_for_rhs: expanding b in ${a[:]=b} is now done as if
|
||||
b were the rhs of an assignment statement. This means that splitting
|
||||
isn't done, but tilde expansion is performed as if the statement
|
||||
were `a=b'. Fixes splitting bug with $* reported by Martijn Dekker

- expand_word_internal: if we see a `:' with the W_NOASSNTILDE flag

set, just add the character and inhibit any subsequent tilde
|

expansion. Currently not set anywhere, but it could be set in
|
||||
expand_string_for_rhs to satisfy its peculiar semantics
