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
hg init
python -c 'print "confuse str.splitlines\nembedded\rnewline"' > a
hg ci -Ama -d '1 0'
echo clean diff >> a
hg ci -mb -d '2 0'
hg diff -r0 -r1
