[PATCH v4 0/1] MR10692: vbscript: Fix Sub first argument parentheses handling (alt parser-only).

[Francis De Brabandere (＠francisdb)]

Alternative to MR !10244 that does the disambiguation entirely in the
parser grammar. The lex keeps master's behavior (no state tracking,
no paren lookahead); a new SimpleStatement production handles the
'CallExpression Arguments OP Expression [, rest]' pattern and
rewrites it as 'f((args) OP expr)' via the action.

Cost: +2 shift/reduce conflicts (12 vs baseline 10).
