the old syntax is not yet deprecated.

748e7dd4c7 Fix calculation of 2**30
In exponent(), 'base *= base;' should not run
when base is 65536, since it overflows an int32_t.

This also optimizes exponent() based on
gcc and clang -O3 test cases in godbolt.org.

d049ffc0f0 Handle string literals within macro arguments (#685)
Fixes #683 and #691

The lexer's raw mode for reading macro args already attempted
to handle semicolons inside string literals, versus outside ones
which start comments. This change reuses the same function for
reading string literals in normal and raw modes, also handling:

- Commas in strings versus between macro args
- Character escapes
- {Interpolations} and \1-\9 args inside vs. outside strings
- Multi-line string literals

Macro args now allow escaping '\', '"', and '\\'.

A consistent model for expanding macro args and interpolations,
within macro args, string literals, and normal context:

- "{S}" should always equal the contents of S
- "\1" should always act like quoting the value of \1

b3c0db218d Remove "EOF-newline" lexer hack
In preparation for an upcoming change
Makes for nicer error messages, complaining about EOF instead of newlines
