Punt on the final space emitted by CMD.EXE's echo on Windows.
It's not just present in buggy implementations,
it's inevitable on all implementations that rely on shell redirection.
Have softer upgrades when upgrading from a forward-compatible-enough version.
NB: insufficiently tested.
Update TODO
Push ASDF3.1 onto features.
Get ready for 3.1.1 release.
Bump version to 3.1.0.26
Add backtrace support for XCL. Unhappily, an XCL compiler bug breaks ASDF3:
The return statement in search-for-system-definition goes awry.
XCL is now officially not supported by ASDF3 (ASDF 2 might still work).
Make asdf-pathname-test more verbose in case of failures,
in the hope that it's easier to understand what's going on.
Bump version to 3.1.0.27
Support XCL again, by working around implementation bugs, documented in TODO.
Bump version to 3.1.0.28
Document another XCL bug.
Fix asdf-pathname-test.script for non-XCL. Oops.
Improve various backtrace implementations.
Bump version to 3.1.0.29
More XCL tweaks.
Bump version to 3.1.0.30
Fix upgrade issue with CLISP from 2.27 to 2.31.
Why is this somehow not affecting other implementations???
Bump version to 3.1.0.31
Make upgrade more robust on CLISP.
Bump version to 3.1.0.32
