Verbose output from compilation recipes had been made more messy by
the previous "simplifying" commit XXX. With this patch, not only we
reduce some code duplication, but also improve that output again, for
the joy of users who dislike silent-rules :-)
* lib/am/depend2.am: Use the new '%XSOURCE%' transform, instead of
copying and pasting the idiom for VPATH rewrite emulation over and
over. Fix some indentation and line-wrapping issues while at it.
* automake.in (handle_languages): Implement the new transform.
* t/silent-nested-vars.sh: Adjust to avoid spurious failures.
