• Fixed #187 differently: doskey.enhanced is true by default again, but if a macro contains $* or $1...$9 tags within quotes then | and & symbols are part of the arguments, not command separators (and expansion stops after that macro).
• Fixed compatibility when doskey.enhanced is false; alias|whatever should not expand alias because there is no space after it.
• Fixed doskey expansion when >& redirection symbol is present; command >& alias should not attempt to expand alias because it's a redirection file name, not a command.
