gnash 1.3.0

A feature release focused on deepening the shell personalities.

Highlights

readline vi editing mode — set -o vi now provides a working vi command mode: motions, d/c/y operators with counts, f/t find, x/r/~/p, undo, and insert-mode entry.
personality / emulate builtin — switch the shell's personality at runtime, with syntax identical to zsh's emulate:
- personality zsh switches live; personality zsh -c '…' runs a command under a personality then restores it; personality -L zsh is local to the enclosing function.
- emulate is the zsh-mode alias.
True-to-zsh parameter expansion (under --personality=zsh):
- No word-splitting of unquoted $var (zsh's SH_WORD_SPLIT off), while command substitution still splits.
- Bare $array expands to all elements.
- 1-based array indexing with negative indices and ranges ($a[1], $a[-1], $a[2,4]), and brace-free subscripts / $#a.
- ${(flags)…} expansion flags (join j/F, split s/f, sort o/O/n, unique u, case L/U/C, keys/values k/v), ${=name} forced splitting, and scalar character/substring indexing.
- Flat key/value associative assignment h=(k1 v1 k2 v2) (also fixes this for the bash personality).
csh/tcsh word-initial tilde expansion — echo ~ and ~user now expand.
