The JGit implementation of getHeadRev did not process filename wildcards,
while the CliGit implementation did. That caused JGit polling of remote
repositories (with the JGit form of "git ls-remote") to always report
there were changes if the branch name included a wildcard, even when
there were no changes.

There are still observable differences in the implementations in corner cases,
since the filename pattern matching implemented in the CliGit C code is only
approximated by a mapping of the * and ? characters to a 0..n character
match and a 1 character match respectively. If the user provides a branch
name which uses other regular expression constructs (like \b, or \d), the
