make introductory message of patch series text/plain

run-tests.py: fix diff output when test-foo.out doesn't exist. Previously, if test-foo.out doesn't exist and test-foo outputs something, the first line of the diff will look like this: -+changeset: 0:0acdaf898367 (note the leading "-")

Allow tests that end in .py and .bat Revision 6ed46bad9530 disallowed tests that have a '.' in the name, but that also disallows tests that end in .py and .bat, even though run-tests.py has some code to special case them.

Merged backout head.

Backed out changeset 2ab464771b7d15c60014996d2853efc92cdb8465 - it always runs chmod - uses chmod in an unsafe way - if somebody does a clone of a repo, runs 'make tests', everything is fine, so he can assume the original repo is fine, too, but it is not.

mq: strip should not blow away local changes This changes the mq strip command to abort if there are any changes in the working directory.

mq: fix qnew and qimport to deal with series file comments qnew and qimport did not take comments into account when deciding where to place new patches in the series file.

mq: qpop should act like quilt pop qpop patchname would pop the named patch off the stack. This is slightly different from how quilt pop works. quilt pop pops everything up to the named patch.
