spock: Error in error message (and missing version number)

[sjamaan]

There's a bug in Spock's read-honu function when it tries to show an error when reading an unbalanced closing delimiter, it will try to append a character to a string with string-append.

Looking at the other calls to err, it looks like the simplest fix is to remove the string-append call and pass the message and character as separate arguments to err:

By the way, spock doesn't specify a version number in its .setup-file which means salmonella shows "unknown" in the list: ​http://tests.call-cc.org/master/linux/x86/2012/05/12/salmonella-report/
