repo_status_test fails with dash

[Peter Johansson]

I get the following log:

=== running ./repo_status_test.sh ===
+ set -e
+ repository_status=1
+ cat /home/peter/src/svndigest-0.10.x/test/repo/db/current

+ [[ 94 -eq 0
./repo_status_test.sh: 38: [[: not found
./repo_status_test.sh: 38: Bad substitution
FAIL repo_status_test.sh (exit status: 2)

I have the same output on a different system where the test works - with svn 1.7 and the same format in the output. The crucial difference seems to be that ubunbtu uses dash instead of bash.

In 1606:

avoid bashism in test code; also replace [TEST] with test TEST (for readability). fixes #534
