bc9d12c4c8 Improve ergonomics of benchsuite. 
The runner now detects if commands exist and permits running incomplete
benchmarks.

Also, explicitly use Python 3 since that's what default Ubuntu 16.04 seems
to want.

d22a3ca3e5 Improve the "bad literal" error message. 
Incidentally, this was done by using the Debug impl for `char` instead

0d14c74e63 Some minor performance tweaks. 
This includes moving basename-only globs into separate regexes. The hope
is that if the regex processes less input, it will be faster.

Aho-Corasick or exact lookups.
