run-tests.py: Show paths to failing tests, .err and .out
I think this is very convenient when investigating and fixing test failures,
but perhaps it must be tweaked further to show paths if and only if
it is appropriate.
#!/bin/sh
mkdir t
cd t
hg init
echo a > a
hg ci -Ama -d '1000000000 0'
echo b > b
hg branch b
hg ci -Amb -d '1000000000 0'
hg co -C 0
echo fast-forward
hg merge b
hg ci -Ammerge -d '1000000000 0'
echo bogus fast-forward should fail
hg merge b
echo done
