7358 unwraps it after seeing this kludgey indicator.

7407 We get here in the READ/BACKEND/ENDFILE/REWIND case "READ(expr)"
7408 with the next token in t. If the next token is possibly a binary
7409 operator, continue processing the outer expression. If the next
7410 token is COMMA, the expression is a parenthesized format specifier.
7411 If the next token is not EOS or SEMICOLON, then because it is not a
7412 binary operator (it is NAME, OPEN_PAREN, &c), the expression is
7413 a unit specifier, and parentheses should not be added to it because
7414 they surround the I/O control list that consists of only the unit
7415 specifier. If the next token is EOS or SEMICOLON, the statement
7416 must be disambiguated by looking at the type of the expression -- a
7417 character expression is a parenthesized format specifier, while a
7418 non-character expression is a unit specifier.
7419
7420 Another issue is how to do the callback so the recipient of the
7421 next token knows how to handle it if it is a COMMA. In all other
7422 cases, disambiguation is straightforward: the same approach as the
7423 above is used.
7424
7425 EXTENSION: in COMMA case, if not pedantic, use same disambiguation
7426 as for EOS/SEMICOLON case; f2c allows "READ (cilist) [[,]iolist]"
7427 and apparently other compilers do, as well, and some code out there
7428 uses this "feature".
7429
7430 19-Feb-91 JCB 1.1
