In a bid to continue simplifying how we write the repetetive bulky parts
of regression tests, I'm changing the sbox.simple_rm() etc. functions to
take path args that are relpaths relative to sbox.wc_dir, instead of
OS-style full paths relative to CWD.
The callers will change from
mu_path = sbox.ospath('A/mu')
sbox.simple_rm(mu_path)
to
sbox.simple_rm('A/mu')
This is just a heads-up, and an opportunity for comments. (I'm not
expecting objections so I'll probably commit it before everyone has a
chance to read this.)
