* Replace some bare uses of cat with ${CAT}
* [ports/19112] Ignore RCS files (*,v) when applying patches
* [ports/19270] Check whether ${DISTDIR} is writable and fail with a
better error message if not (mostly caused by trying to fetch as the
wrong user)
* [ports/23560] Force patch backup files to be created with .orig suffix
* [ports/34717] Don't enclose PTHREAD_LIBS in quotes, because it will
cause problems if used in an already-quoted string.
* [ports/34987] Fix an awk warning in MASTER_SORT/MASTER_SORT_REGEX code
* [misc/38724] Change some uses of the deprecated test -h to test -L
* [1] Registering real dependencies: dependency registration looks at the
currently-installed version of the dependency and registers that version,
instead of registering the version in ports which may be newer than
what is installed.
* [2] Further 100% speed-up of dependency registration process by eliminating
second call to package-depends (using information from the first call
stored in +CONTENTS file of package being installed). Very useful
for developing GNOME or similar packages with zillion dependencies,
when package-depends target could take few minutes to complete;
* [2] Proper set-up of ${SHELL} variable in build environment, so that user's
interactive shell isn't picked instead. This has various implications,
ranging from build process speed-up due to using /bin/sh to invoke
libtool instead of bash or any other much more bloated user's shell
(configure scripts often pick it up from the ${SHELL} environment),
to fixing problems some users have when building random ports.
