ISSOtm 2eca43cd2d Fix critical oversight in lexer buffer refilling 
Since the lexer buffer wraps, the refilling gets handled in two steps:
First, iff the buffer would wrap, the buffer is refilled until its end.
Then, if more characters are requested, that amount is refilled too.

An important detail is that `read()` may not return as many characters as
requested; for this reason, the first step checks if its `read()` was
"full", and skips the second step otherwise.
This is also where a bug lied.

After a *lot* of trying, I eventually managed to reproduce the bug on an
OpenBSD VM, and after adding a couple of `assert`s in `peekInternal`, this
is what happened, starting at line 724:

0. `lexerState->nbChars` is 0, `lexerState->index` is 19;
1. We end up with `target` = 42, and `writeIndex` = 19;
2. 42 + 19 is greater than `LEXER_BUF_SIZE` (= 42), so the `if` is entered;
3. Within the first `readChars`, **`read` only returns 16 bytes**,
   advancing `writeIndex` to 35 and `target` to 26;
4. Within the second `readChars`, a `read(26)` is issued, overflowing the
   buffer.

The bug should be clear now: **the check at line 750 failed to work!** Why?
Because `readChars` modifies `writeIndex`.
The fix is simply to cache the number of characters expected, and use that.

ISSOtm 930080f556 Mark not unmapping macro-containing files as okay 
There isn't really a better alternative.
Making several mappings instead requires too much bookkeeping.
