expand_aliases_in_sandbox

(expand_aliases_in_sandbox ...)

When a sandboxed action depends on an alias, copy the expansion of the alias inside the sandbox. For instance, in the following example:

(alias
 (name foo)
 (deps ../x))

(cram
 (deps (alias foo)))

File x will be visible inside the Cram test if and only if this option is enabled. This option is a better default in general; however, it currently causes Cram tests to run noticeably slower. So it is disabled by default until the performance issue with Cram test is fixed.
