tests: Solaris sed does not support "\n" meaning newline in the RHS of s/// The blackbox test rewrites a copy of test-dispatch.py on the fly, and adds a couple of lines with the s/// command. GNU sed supports the use of the \n escape to represent a newline, but not Solaris sed. Using a literal newline, prefixed by a backslash, works with both versions of the utility.

tests: Solaris cp doesn't support the -T option The treemanifest tests use the -T option to cp in order to ensure that the two directories named on the commandline are treated as peers, rather than the usual behavior when the final argument is a directory. GNU cp has this option, but other implementations may not. Thankfully, there's no pressing reason to use it. We can simply copy the contents of the first directory into the target directory, since we know that the target directory already exists.

templater: make date() use helper function to evaluate argument A date argument should never be a generator, but using evalfuncarg() should be good for consistency.

templater: fix revset() to evaluate format arguments eagerly See the previous patch for why. This patch also removes redundant list() construction from a list.

templater: fix ifcontains() to evaluate items argument eagerly See the previous patch for why. An "items" argument may be a string, a generator, or an arbitrary container object.

templater: fix get() to evaluate arguments eagerly If a key is constructed from a template expression, it may be a generator. In that case, a key have to be stringified. A dictarg should never be a generator, but this patch also changes it to call evalfuncarg() for consistency.
