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.
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.
I got tired of trying to guess how much terminal time I could get in on my phone, so here's a basic acpi.

I could probably add -c fairly easily (print type, cur_state, and max_state)
-t is more difficult, since temperatures are reported in at least
1000 * degrees F and 10 * degrees C.
Cleanup on acpi, switch to default y.
Remove two unused functions and shrink another.
First pass of cut cleanup, and make test script slightly happier with the concept of 80 character lines.
Ah, that's why commit 1057 was skipped last pull: it was unfinished. Oops. (Fix it.)
