test-dispatch: Make test of removed working directory work on AIX (
issue2315)
AIX sh won't delete its own working directory. Removing it from another process
works.
Also hide the actual OS error message - operating systems returns different
errors when getcwd fails.
#!/bin/sh
rm -rf a
hg init a
cd a
echo foo > foo
hg ci -qAm0
chmod +x foo
hg ci -m1
hg co -q 0
echo dirty > foo
hg up -c
hg up -q
cat foo
hg st -A
echo '% validate update of standalone execute bit change'
hg up -C 0
chmod -x foo
hg ci -m removeexec
hg up -C 0
