Don't pad stat's %a field.
fix rm to handle "mkdir sub/sub && chmod 007 sub/sub && rm -rf sub".

Previous version didn't delete it, but exited without error. Neither was right.
Make chdir handle permissions according to posix, reported by Jacek Bukarewicz..
env - there were 2 segfaults when run on my Ubuntu 12.04 machine:
    - one is because eglibc sets environ to NULL on clearenv(). I added check for environ being not NULL when iterating over environment variables
    - switched xexec to xexec_optargs because command argument is a pointer to optarg which is freed by xexec.
uname: Fix help string
make.sh: Fix probing for python2.x and be verbose in error reporting
Replace for_each_pid_with_name_in_array_perform_callback_function_upon_translated_value() with name_to_pid(), comparing absolute paths or just basename() consistently as spotted by Lukasz Skalski, and adjust callers.
Allow shipped generated/help.h to still be used, until I rewrite the generator in C.
Missing typecast in recent rm fix. Oops.
Fix for xpidfile spotted by Felix Janda.
Make [-abc] exclude logic clear argument slots when disabling options.
Ashwini Sharma submitted route.c, adding it to pending.
Pending cleanup page, less than half done. Some of it should probably move to the code style section.
Merge branch 'master' into build
Fix [-group] argument dropping.
Redo tail closer to the original design. Add more tests for large data sets. (Still no -f support yet.)
Adjust patch to use dlist_pop()
Minor cosmetic tweaks to expand.

Working my way through the to-review list that predates the "pending"
directory. This gets expand off my to-review list. (Proof that "need to
review" doesn't mean it's in bad shape, this command was fine. Changed
capitalization in the help text because I'm trying to have "user supplies
this value" be all caps, switched a read() to readall() although I'm not
sure modern kernels actually allow -EINTR to generate zero length reads
anymore, and since most of the loopfiles() target functions are called
do_commandname() changed the name to that just so it's regular. None of
the changes are actually important. :)
Don't write a zero past end of toybuf with large -d value.
Minor cleanups.
