7304420691 fix peek implementation in R6RS input ports 
The peek operation must not block, otherwise the port behaves
badly for `sync`.

Based on a bug report from Brett Stahlman.

c627b0fc6f pict: make hc-append, etc., match the docs 
Allow pict arguments, with or without a separation-size
argument.

The recently added contract has rules out providing a
separation size with no arguments, which had been allowed
before. The underlying problem, though, was an inconsistency
in the implementation that allowed 0 pict arguments only
in the case that a separation size is provided.

dcfe7ede67 make some arity error messages for ->i contracted functions 
slightly less terrible

... but ->i still doesn't do as good a job as -> and ->* do for arity
errors (specifically, ->i is still letting the blame-less errors that
application constructs thru when it could be assigning blame)

1542398822 optimizer: move more things inside let and begin 
Refactor the code to move inside 'let' or 'begin'.

Also, in the test position of a 'if', recognize the 'not' inside a 'let' or 'begin'.
For example, transform (if (begin ... (not p)) x y) => (if (begin ... p) y x)
Previously, this conversion was made only when
the 'not' was the outermost expression.

And use the refactored code to move application inside 'let' or 'begin' in a single step
For example, transform ((let (...) ... (let (...) ... f) x) => (let (...) ... (let (...) ... (f x))
In the conversion, it's necessary to shift x to the new coordinates inside the 'let's.
In the new version x is shifted only once.
