[PATCH v2 2/3] difftool: avoid double slashes in symlink targets

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When we add tests for symlinks in "git difftool --dir-diff" it's easier
to check the target path if we don't have to worry about double slashes
separating directories.  Remove the trailing slash (if present) from
$workdir before creating the symlinks in order to avoid this.
