Comment(by leif):
It is not immediately clear why using `pwd -P`, which fully expands
symbolic links, and therefore would canonicalize `$SAGE_ROOT` as well,
should break doctesting.
Even if it did somehow, this should be addressed in the corresponding
scripts, `sage-{test,ptest,doctest}`, which are currently under work
anyway, and have certainly changed since #5852 was opened (or last
modified).
Taking the canonical path of both the files to test and `$SAGE_ROOT` (or,
more precisely, of the current branch of its Sage library), there
shouldn't be any ambiguity in distinguishing Sage library code from other
code. We also meanwhile have an option `-force_lib` to `sage -t` and its
friends.
Slashs, dashs etc. from paths of files to test should never end up in an
`import` statement, and I don't think they currently could, as we copy
source files anyway.
