One would think that for dabbrev-expand, in shell scripts, it should
be sensitized to a major expansion candidate: shell variables.
For instance, typing
using the keystrokes
v a r _ n a m e = w o w RET v a r 2 = $ v ESC /
instead of failure of expansion, a better syntax table [?] would be aware
that $ can be separated from the expansion candidate.
