minor cleanups

Browse source 
* libguile/stacks.c (scm_make_stack): Instead of aborting when we misread
  the number of stack frames, just print a warning. I'd like to figure
  out what these cases are, exactly.

* module/language/scheme/compile-ghil.scm (lambda): Reindent the lambda
  transformer.

* module/system/base/compile.scm (call-with-compile-error-catch): Write
  the expression instead of displaying it.
  (call-with-output-file/atomic): Don't actually redirect output to this
  port, as it's not necessary -- the language-printer should respect the
  port that we pass.
